Arsenal goalkeeper Petr Cech has paid tribute to former Chelsea coach Christophe Lollichon.
Cech reckons ex-Blues coach Lollichon helped transform him into one of the best shotstoppers in Premier League history.
"I always did my research and always did my preparation, but I think we went up another level once I started working with Christophe Lollichon," he told Arsenal magazine.
"We really went into details.
"This is how we approached the situation.
"I came over here and we did the same thing. You prepare, you watch the analysis of the other team, their free-kicks, corners and penalties, and all their attacking situations. Everywhere is the same."
