Jenson Button said he is cautiously optimistic that McLaren will be competitive in Monaco following Thursday's practice sessions.

While the majority of FP2 was wet, Button was 11th quickest in the first session and 0.3s off his team-mate Kevin Magnussen in ninth. With McLaren not having scored a point for three races it looks set to be able to challenge for the top ten this weekend and Button said the early signs were promising even if he is still unsure of the car's outright pace.

"It's alright actually, I don't know how fast we are but the feeling is nice," Button said. "It's nice to be back around Monaco; it's a crazy circuit really but it's a lot of fun. In the dry it's nice with these cars actually, with the power. There's not a lot of mechanical grip though, which is always difficult with the tyres that we have but the supersoft is a reasonable tyre so it's not so bad.

"The inters are very difficult. Even when the circuit is almost dry there's no grip at all. I was wheelspinning in fifth gear so it's something that is unusual to us when you're normally so confident to hit the throttle hard, but it's the same for all of us. It's nice to get out around the principality; I just hope for some dry weather on Saturday morning because we haven't had much set-up work."

And Button added that a good performance would be a nice boost for the McLaren team working back at the headquarters in Woking.

"There's still more progress to be made with the car. I know that all the guys are working flat-out back at the MTC so it would be nice to give them a reasonable result so that we can progress from here and keep developing."
