Lewis Hamilton just needs more time to feel comfortable in Mercedes, says Ross Brawn

Mercedes boss Ross Brawn remains confident it is just a matter of time before Lewis Hamilton feels fully at home in his new team's car in the wake of Hamilton's surprise admission that he was "struggling" with the W04.

"We want both our drivers when they're not ahead saying that they've got to improve, they want to find ways of getting more out of the package, more out of the car, more out of themselves and more out of the team. So that's what we want." Elaborating on his current difficulties in wake of qualifying, Hamilton explained that it was certain features and characteristics of his new car compared to the McLaren that were taking time to adapt to. "The set-up I have on the car in terms of brake cylinders and all these kind of things, steering wheel is a lot different to what I experienced before where I was very, very comfortable and been there for years so I was used to it and it was always the same. That's been a slight weakness for me this year." The 2008 title winner admitted he didn't currently have the level of confidence in the W04 needed to really go on the attack around a circuit such as Monaco, adding that unusually for him tyre temperatures had been a problem up until his final Q3 lap. "It's nothing really to do with the engineers, it's just a general feeling with me. It's difficult to really explain it; I've just not been on it all weekend," Hamilton added. "It's not through not being focused, it's not being centred or anything like that it's just being comfortable in the car. "When I was at McLaren I'd obviously been there for a long, long time. I had 100% confidence in the car - particularly this track where you need 100% confidence in the car beneath you. It worked well in the past it's just I've been struggling with getting that confidence which means you can't break late enough. "I think what has really contributed to it is tyre temperatures; I couldn't get enough temperature into the tyres this weekend up until the second and third sector of my last lap and that's the best the car has felt all weekend. "So perhaps if I'd got them switched on maybe a bit earlier in practice I'd have had a better understanding of how to get them up to temperature. That's the first time I've ever really struggled to get temperature into my tyres and especially with our car." The 2013 Monaco Grand Prix this weekend is live only on Sky Sports F1.
