During his two decades in charge, the Frenchman has played his part in developing household names like Thierry Henry, Nicolas Anelka, Freddie Ljungberg, Robert Pires and Patrick Vieira.

On the weekend when he celebrates 20 years at the helm, the Gunners boss has heaped praise on centre-back Laurent Koscielny.
The France international, 31, was virtually unheard of outside his home country when he joined from Lorient in 2010 but he has become a rock at the heart of the Arsenal defence.
Wenger gave pens to journalists to mark the anniversary at his press conference in the week.
