For someone with so much versatility - such fluid yet mechanical movement - it's a perennial puzzle why the world No.5 hasn't had more success on the terre battue. Out of his 20 titles, claimed in 20 different cities, only one of those triumphs has been on clay. It was a pretty significant one, having ruled the Rome Masters last May.
"I don't like footwork on clay, that's for sure. There are many reasons for that but I think this is because I am very light, not heavy enough on my legs. In Roland-Garros, this is fine but on other types of clay, I can't stop sliding. So, I slide well but I keep sliding while the ball goes the other way. It was quite frustrating honestly to play like this," explained the world No.5.
"On hard surfaces, I have one of the best footwork on tour whereas on clay, the rally is over as soon as my opponent hits a good shot. It was a bit hard mentally to accept this, but in the last years I managed to work on this: sliding, moving and having the right mindset on clay.
"I'm not going to say that I like it but I don't hate it. I'm trying my best and my best is sometimes good, even on clay."
