Red Bull boss Christian Horner has conceded his team may have to endure a slow start to the new F1 season. The former world champions unveiled a revised car livery for the new season at a launch event in Londons Brick Lane on Wednesday, although their new RB12 car is being kept under wraps until the opening day of testing on Monday.Red Bull, after months of uncertainty and political wrangling, have ended up continuing with Renault engines for 2016, but Horner has previously warned they face a transitional season while the French manufacturers work on finding a breakthrough for their struggles. And asked at the launch if he still expected a transitional year, Horner replied: I believe it will be. We are going to start the year hopefully with some progress from the end of last year, but with our engine partners commitment to buying a team now, were hoping to see staged progress during the course of the year.We are hopefully going to see a steady rate of improvement, so probably the second half of the year is going to be more competitive than the first half. Red Bull have gone for a matt finish on their 2016 livery After salvaging second place to Mercedes in the Constructors Championship in the first year of F1s turbo regulations in 2014, Red Bull were also overhauled by Ferrari and Williams last year and Horner is again expecting 2015s leading teams to be strong.However, echoing Red Bull technical chief Adrian Newey, Horner also hinted that sister team Toro Rosso could pose an early threat too following their switch to Ferrari power.We know that Mercedes and Ferrari are going to be strong because even if they did nothing, theyre still going to be in good shape, Horner said. Red Bulls new 2016 look F1s former champions go aggressive in design of new livery Its difficult to know. How much have Williams found? What have Force India done? Weve just got to focus on ourselves.We know Toro Rosso, for example, will make a big step. Weve just got to focus on ourselves and do the best job we can.Despite the Red Bull-Renault relationship lurching to the brink of divorce in 2015, its continuation on revised terms for at least one more season means the short-term success of the Milton Keynes team is still largely wedded to the competitiveness of the French carmakers engine.But despite Renaults winter takeover of Lotus re-establishing themselves as an F1 constructor, Horner insists he is not worried his team will now receive inferior treatment. Red Bull have unveiled their new car for the 2016 season We know well get the same product from Renault that the works team will get, he said.Lets not forget, we won a World Championship when they had a works team in 2010 so Im not worried about there being a differentiation in treatment. The most critical thing is that theyve made progress with performance and that hopefully will happen throughout the year.With Renault having played down their own chances in 2016, Red Bulls aerodynamic package will again prove particularly key in their attempts to mix it at the front of the grid.Horner revealed the team had pushed the mandatory crash testing for the RB12 right up to the limit ahead of next weeks opening test.Were probably the latest team to do any of the crash tests, which have all been done this week, he said. They started on Monday and finished about an hour ago and were ready to go testing in Barcelona. Hats off to everybody in the team for having done a fantastic job.The first Barcelona test starts on Monday February 22 and the Sky Sports F1 Digital team will be providing live commentary from dawn until dusk on all four days of both Barcelona tests while Sky Sports News HQ will also deliver live updates from trackside.

Isner, ranked No. 14, won his eighth career singles title and took the title in New Zealand for the second time after his victory in 2010. The match was similar to Isners quarterfinal victory over fifth-seeded Philipp Kohlschreiber which went to three sets, all tiebreaks and contained no breaks of serve. The showdown between two of the NFLs hottest teams could be decided by a single digit. In this case, that digit happens to be the middle finger on Matthew Staffords throwing hand.Stafford reportedly suffered torn ligaments and a dislocation in the first quarter of the Detroit Lions 20-17 win over Chicago last Sunday. He threw two interceptions, including a pick six, after having the finger taped and putting a glove on his hand. Stafford still led his club to its eighth fourth-quarter comeback victory, the most by any team since the AFL-NFL merger in 1970.Detroit, which leads the NFC North, will try to extend its winning streak to six games when it faces the New York Giants at MetLife Stadium. The Giants have won seven of their last eight games, including a gritty 10-7 victory over NFC East leader Dallas last Sunday night.I expect it to be extremely competitive, Stafford said. Theyre playing for a lot and were playing for a lot. Its an NFC game and its going to be a big one. So were excited for the opportunity. Its great to be in this position; weve just got to go out there and play well.His finger complicates that process. The Lions pedestrian running game puts added pressure on Stafford to carry the offense. Hes ninth in the league in both completion percentage (66.7) and passing yards (3,447). Hes also tossed 22 touchdown passes and was intercepted just five times prior to the injury.Stafford, who scored the game-winning touchdown against the Bears with a 7-yard scramble, hopes the injury will be less of an issue with a week to experiment on equipment and treatment options. Hes unsure whether hell wear a glove against the Giants. An early forecast of inclement weather could force another in-game adjustment.Its never fun when its on your throwing hand but Ill figure it out and well go from there, he said. (The glove) is not really for my state of mind, its for whats going to be functional. So whatevers most functional, with what I can perform the best with, thats what Ill go with.Staffords job wont be any easier if Detroit is missing its leading rusher once again. Theo Riddick, who is most effective as a receiver out of the backfield, sat out against the Bears with wrist and ankle injuries and is doubtful. One of his backups, Zach Zenner, is in the leagues concussion protocol and is questionable.With three games remaining, the Lions (9-4) could wrap up their firstt NFC North title with a victory on Sunday and a Green Bay loss.dddddddddddd The Packers and Minnesota Vikings are tied for second place with 7-6 records and Detroit already holds the tiebreaker over Minnesota after sweeping the season series.The Lions dont have any soft touches remaining on the schedule. They have to play the Cowboys in Dallas the night after Christmas, then face the Packers at home on New Years Day.In head coach Jim Caldwells mind, the upcoming games arent any different from the ones his team just played.It didnt matter what the Bears record was last week, he said. That game still had a lot of magnitude. It was very, very important. This one is exactly the same. It just so happens, and thats how its going to be down the stretch, that youve got a team thats playing very, very well and thats riding high.The Giants (9-4) kept their division title hopes alive by defeating the Cowboys for the second time this season. They diffused the Dallas attack despite the absence of defensive end Jason Pierre-Paul, who underwent sports hernia surgery last week and is expected to miss the remainder of the regular season. New York forced three turnovers, sacked rookie quarterback Dak Prescott three times and held Dallas to 260 total yards.Other than the crossing route that wide receiver Odell Beckham turned into a 61-yard touchdown reception, the Giants offense was a virtual no-show on Sunday. Quarterback Eli Manning threw an interception and lost two fumbles and the rushing game averaged 2.8 yards per carry.Ive got to play better, Manning said. Got to find completions, got to protect the football better. Thats whats got to happen in these types of games. You get into December, youve got to protect the football. Thats the most important thing right now.Manning was also picked off twice the previous week in a 24-14 loss to Pittsburgh and has thrown for fewer than 200 yards in the last three games. Fortunately for him, the defense has masked the offenses struggles. Opponents have been held to 20 or fewer points in five of the teams last six victories.Weve got to keep finding ways to win, he said. The defense is playing outstanding, so weve got to help them out. Weve got to score more points, give them a lead and dont make it hard on them. ' ' '
