I could've swore he made his name at Monaco mind you. What do I know.
He did indeed. He'd been doing great stuff for 10 years as a manager before he came here.
Did he get to the CL final and win the league? Genuine question, I don't know. Mourinho, Klopp, Guardiola & Conte have all done that before coming to England.
I was under the impression Wenger had done some great things prior to Arsenal but nothing to indicate he would win multiple titles and get to the final of the CL.
Fairly sure he won a French title with Monaco with Hoddle and Hateley despite Marseilles being the dominant side then.
