Jenson Button is hoping the 'happy-pill effect' he witnessed at McLaren 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."
