Chela has had a tough battle to get back among the world's best players after he was banned from the game for three months and thrown out of the top 500 for failing a drugs test.

He has come back to the fore on his return this season and is part of a new breed of talent that Argentina has produced in recent years.

His favourite surface is undoubtedly clay although he lost out to Tim Henman in the Tennis Masters Series recently.

And he could be among those to cause an upset at Roland Garros.
