Arsenal boss Arsene Wenger is happy for Andre Villas-Boas over his success at Tottenham.

Villas-Boas enjoyed great success with Porto before moving to the Premier League and Wenger believes he has shown his worth.

"He has done well," the Arsenal manager told arsenal.com. "I think he has done well.

"For the rest, I don't know how life is on a daily basis [at Tottenham]. It is very difficult to assess that. But they play well. They are a good side. They have renewed a lot their team and they are doing quite well.

"Villas-Boas got a deserved second chance," added Wenger. "Sometimes you get the second job because you got the first one.

"For example, it would have been maybe more difficult to get the Tottenham job if he had not had the Chelsea job before because people could watch him and see what he has done and speak to players who have worked with him.

"So, you have bit more of a guarantee than just importing someone from Portugal."
