Stanislas Wawrinka admitted he is struggling to piece together the puzzle of life as a grand slam champion after crashing out of the French Open in the first round.
The Australian Open winner and third seed never looked comfortable in heavy conditions after a wet day in Paris and fell 6-4 5-7 6-2 6-0 to Spain's Guillermo Garcia-Lopez.
When Wawrinka lifted his first Masters trophy in Monte Carlo last month it looked like he could potentially add the French Open crown to the one he so stunningly won in Melbourne in January.
But he was in trouble virtually from the start on Court Philippe Chatrier and became the first Australian Open champion to lose in the opening round in Paris since Petr Korda in 1998.
Wawrinka said: "I was completely flat. I was not really relaxed with my game. I wasn't aggressive. I was playing some bad rallies. Everything was terrible.
"I always put a lot of pressure on myself. But before the match and during the match it was not really about only the pressure.
"I think it's just a different story. Now it's a different picture for my career. I need to put the puzzle back together, but differently than in the past.
"Because now it's after winning grand slam, Masters 1000, being number three in the world. Everything is different, and I still didn't find all the pieces."
