Manchester United midfielder Tom Cleverley has suffered a new injury setback.
The 22-year-old midfielder was replaced by Paul Scholes an hour into United's 2-1 Europa League defeat to the Dutch champions. He made his return to action seven days earlier, in the first leg in Amsterdam, after almost four months out with a foot injury.
Sir Alex Ferguson told MUTV on Friday afternoon: "He got a knock. We sent him for a scan but we don't think it's serious."
