Patrik Berger has backed Aston Villa boss Martin O'Neill's cautious approach to the market.

"I think it's better to have two quality players than four average players," Berger told Sky Sports News. "He (O'Neill) has bought two very good players [Nigel Reo-Coker and Marlon Harewood] and there are still a couple of weeks to go before the deadline.

"He is a very smart man and I am sure he will bring a few more faces in."
