Despite getting well inside the top ten in a free practice session for the first time this season, Jenson Button was playing down the much discussed gains made by McLaren-Honda following free practice, insisting it has been a 'weird day'.

With the team having pledged to bring significant updates to its package ahead of the first European round of 2015 - as well as a new black livery -, though Button and Fernando Alonso were down the order in FP1, Button made big gains in FP2, going seventh fastest when on the softer tyre.

Despite this, the former champion was philosophical about the result, signalling concern with the car's performance on the prime tyre in FP2.

It's been a good day in terms of data but there's a lot of work to do to figure out why the car is doing certain things.

Indeed, though Button was certainly pleased to see P7 alongside his name after FP2, he maintains you cannot read too much into free practice.

"It's still only practice. We always seem quicker in P2 than in qualifying. We'll see, hopefully we can have a clean weekend and then we'll see where we stand. I'd say it's a promising day when you compare us to the front guys anyway."
