Manchester United boss David Moyes played down Robin van Persie's injury suffered in victory over Olympiakos.

The Dutchman was the hero for Moyes' men as he scored a hat-trick to guide United to a 3-0 win and a 3-2 aggregate victory against their Greek opposition, but his night was cut short when he was caught by Ioannis Maniatis.

Speaking to Sky Sports, Moyes said: "It (the injury) doesn't look that bad. It may have been just a knee in the back."
