Arsene Wenger not only revolutionised Arsenal when he arrived at Highbury in 1996, he revolutionised English football too.Le Professeur, as he would become known, introduced new preparation methods, training drills and tactical ideas that had never been seen or thought of before in Blighty - the home of 'get rid of it, son' and 'get stuck in, lads!'.What also caught everyone's eye was Wenger's penchant for foreign players.
