Jenson Button says there is no need for Fernando Alonso to raise his game in the 2014 F1 season, arguing that the Ferrari man is already at his prime.
Alonso will face a new challenge next year when Kimi Raikkonen rejoins the team from Lotus, having inked a two-year deal to replace Felipe Massa.
Many expect the battle between the two drivers to be one of the main talking points of 2014, with some suggesting that Alonso will need to raise his game to see off the challenge of his new team-mate.
Button however said he didn't think that would be the case.
“It's going to be interesting to watch, as I keep seeing people saying that Fernando will lift his game,” he said. “I don't think he will, simply because he can't, nor he shouldn't be able to.
“Fernando is at his prime and should be giving his all, which I think he is doing. It might help Ferrari having two fast drivers when it comes to data and feedback, and with the points. They could get on a like a house on fire, or it could the opposite. It'll be interesting to watch.”
Button himself has first hand experience of working alongside another champion from the time he first signed with McLaren, and admitted it had been easy to come to terms with that he expected.
“When I arrived here, I had been with a team for seven years who I knew and they knew me,” he said. “I was going to a team that was new, and Lewis had been here almost from the moment he could walk! However, I felt at home and there were no issues, they back me just as much as they backed Lewis.
“It's all about finding your feet and isn't just a case of driving the car quickly. It's about working with the guys and the engineering side of things to become part of the team and I did that early when I arrived.”
