Diego Schwartzman spoke after beating Jan-Lennard Struff 7-6, 6-4, 7-5 to reach the French Open quarter-final on Monday. The Argentine arrived at Roland Garros on a four-match losing streak but found his rhythm and is set to play defending champion Rafael Nadal for the 12th time. He has only won one tie so far and will be looking to beat the King of Clay again as playing against Nadal tells you "how good you are playing".
