Arsenal defender Laurent Koscielny has hailed the quality of Tomas Rosicky.
Rosicky inked new terms with the Gunners this week.
Koscielny told Arsenal Player: "Tomas Rosicky, you know his nickname, little Mozart, and I think he's a player who is very important for us.
"When he's fit, it's amazing, he can make the difference alone. He scored so many important goals. Like the last one where he played one touch with Santi, Jack and Olivier. He has the technique to play and to give for the team and to make the difference."
