"You also saw it again the other night in the Chelsea v Barcelona game. We're in an age where you're almost expecting it now.
"You get bad decisions and you get good decisions. It evens itself out, believe me. It's the same for everybody.
"We didn't get [a penalty kick] against Wigan last week but we didn't scream from the rooftops about it. We realise it happens. We got a penalty kick against us when we played Newcastle which was never a penalty kick. We had an apology from Mike Riley for that. It happens."

Sir Alex would appear to agree.
"We have a player here who stays on his feet and he's been doing that for 20 years. How many penalty kicks has Ryan Giggs won for Manchester United?
"He's won five in 20 years. That's some record. Do you know why? Because his balance is so good and he never goes down. That's the amazing thing about him."
