Federer clinched the career Grand Slam when he beat Robin Soderling in straight sets 12 months ago to claim his maiden Roland Garros crown.
The Paris major had been the only slam to elude him in his illustrious career, indeed critics said it was the tournament which would define whether he could truly call himself the best ever.
Since that success, the Swiss maestro has reclaimed the number one status after clinching his sixth Wimbledon trophy and in doing so, became the men's leading major winner beyond the legendary Pete Sampras.
But the 16-time slam champion heads into this year's tournament as the second favourite with his nemesis Rafael Nadal back to his best.
The pair met in the final of the Madrid Masters, in what appeared a dress-rehearsal for Paris' second-Sunday fixture and it was Nadal who prevailed in straight sets.
That means the 28-year-old heads into the second major of the season without a tournament win on clay in 2010 after failing to reign in Monte Carlo, Rome or Estoril.
Federer has contested the last four finals at the French Open and history suggests the world number one will be there for number five this year.
