Wenger feels Villas-Boas took the Chelsea job too soon.
He said, "He may have been a little young at the time when he came to Chelsea. He took little break and sometimes it does not hurt in mid-career. From what I have seen since the beginning of the season, his team has the desire.
"It is a little limited in potential. Marseille today does not have the level to play the title of champion of France. But he managed to get the team behind him and instill a dynamic in the team. If he finishes in the first six, I think he has really had a good season."
