Basel to qualify for the CL knockout rounds?

Basel have given themselves real hope of qualifying for the Champions League knockout rounds following their unexpected win over United.

They now sit in joint second place, alongside CSKA Moscow, and can guarantee their place in the next round with victory over Benfica in two weeks time.

Benfica currently occupy bottom spot in Group A, having lost all five of their matches so far.

"I don't want to talk too much about the opponent," Basel head coach Raphael Wicky said after beating Man Utd. "We deserved the victory. We played hard and deserved this victory."
