Manchester United manager Sir Alex Ferguson blasted referee Olegario Benquerenca for not awarding his side a penalty in the 3-3 draw with CSKA Moscow in the Champions League Group C match at Old Trafford.

The draw was enough to take United through to the last 16 but Ferguson was far from happy not to get a spot kick when Darren Fletcher appeared to be tripped in the area, the Scottish midfielder instead being booked for diving.

Ferguson said of the decision not to award a penalty: "I can't believe it. I can't believe the decision. It's one of the worst I've seen in my lifetime."

Michael Owen (29) had equalised for Untied before the visitors went 3-1 up. Paul Scholes netted with six minutes to go and Antonio Valencia's shot in added time was deflected in.

A breathless Ferguson added on Sky Sports 2: "I need 10 minutes to think about that. Their goalkeeper made some fantastic saves.

"I thought the intensity of our play, and particularly in the last 25 minutes, was terrific."
