Andy Murray is expecting a difficult test from Philipp Kohlschreiber when they meet Saturday in the third round of the French Open.
Murray cruised past Australian Marinko Matosevic 6-3, 6-1, 6-3 on Thursday. Kohlschreiber, seeded 28th, also won in straight sets against Denis Istomin.
Kohlschreiber won his first title of 2014 in Stuttgart last week. Murray, the seventh seed at Roland Garros, does not have happy memories of his previous clash on clay against the German.
It will be "a very tough match for me," Murray said.
"I played him once before on clay and I think I got three games or something.
"I remember not playing particularly well. I was very disappointed after the match.
"(At the) beginning of the clay-court season I have had some tough matches over the years, so I don't remember a whole lot about it in terms of exactly what happened during the match. It just wasn't a pleasant memory for me.
"It will be very tough. He obviously won the tournament last week. He's not dropped a set here, I don't think. So, yeah, he will be very tough. (He is a) very good player."
