Jenson Button is hoping the 'happy-pill effect' he witnessed at McLaren yesterday will continue to take hold throughout this weekend's Turkish Grand Prix.

Button was bowled over by the atmosphere within the team on his arrival at the Istanbul Park, in particular given the sad end to the last race in Monaco 12 days ago.

On that occasion world champion Button retired at the start of lap three with an overheating engine caused by a member of the team leaving a foam bung in a sidepod over the radiator.

The mistake resulted in Button losing his championship lead, and with team-mate Lewis Hamilton only finishing fifth, McLaren were also deposed from the top of the constructors' standings.

That could have resulted in an air of doom and gloom pervading the McLaren motorhome in the build up to Sunday's race, only for Button to discover the complete opposite.

"I wandered in and I thought, 'What is everyone doing? Are they all on happy pills or something?'" said Button.

"There is a really good atmosphere in the place at the moment and we are looking forward to seeing how the car goes here.

"It seems everyone is just excited to get under way again. We're moving on from Monaco and intent on showing what we can do.

"Monaco was obviously a tough weekend, and I am happy what happened to me happened on lap two instead of lap 62.

"But I have been doing some training this week, some PR, and I am in a really good place right now and really excited about getting back out there.

"When you have a race like that, where you don't even compete, it is frustrating, but you also cannot wait to get back out there and jump in a car."

The topic dominating the thoughts of many of the leading drivers is whether Red Bull's Mark Webber and Sebastian Vettel can finally be stopped.

The duo have claimed pole - three apiece - in each of the six races this season, and the suggestion is they are likely to make it seven in a row in qualifying tomorrow.

"If you look at the last few races there is one team that has stood out, and that has been the Red Bulls, so it is about chasing them down," added Button.

"They showed in the last two races when they don't make mistakes and don't have reliability issues, they are pretty tough to beat.

"At Barcelona and Monaco nobody else had a look-in really. I hope it is not the same here. We will have to wait and see."
