Mercedes team boss Ross Brawn has conceded that the new MGP W01 wasn't as quick as he had hoped ౠthis week during testing at Valencia in Spain.

Michael Schumacher and Nico Rosberg both drove for the Brackley-based outfওit - former 2009 F1 titܫle winners Brawn GP - over the three-days. However the team's best lap, a 1 minute 12.438 seconds - set by record-breaking multiple F1 world champion Schumacher - left them only seventh on the combined times.

"On full tanks we didn't look too bad but we are a little bit off the pace," Brawn told BBC Sport. "The handling and balance of the car is not quite right, but we can fix it 𓄧for Jerez. We know what the problem is.

"Of course the other teams will be progressing as well. We are not as quick as Ferrari, and Lewis Hamilton looked ᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚquick on Tuesday for McLaren, so it looks ♍like we have got a bit of work to do.

"We are cracking exhausts and we have to change those every 150-200 kilometres. It is a🥀 problem we can fix but here it is difficult.

"We've got a handling imbalance because we are all lea༺rning about these tyres here and we've seen straight away some thin💞gs we want done on the tyres which we will have done by Jerez."

F1 2010 testing continues next week at Jerez with runningꦗ commencing on February 1꧃0 and concluding on February 13.
