Nemanja Vidic has admitted it will be a few weeks yet before he is back to top form.
The Manchester United skipper made an eagerly-awaited comeback from his cruciate operation in Norway on Sunday.
Vidic managed an hour of the 0-0 friendly draw with Valerenga in Oslo without a problem and is expected to play on Wednesday, when United take on Barcelona in Gothenburg.
With the Red Devils set to open their Premier League campaign against Everton at Goodison Park in a fortnight, Vidic needs to build up his fitness quickly.
The 30-year-old told MUTV: "After eight months without a game it's obvious that you have to get used to your positioning. Fitness-wise it's not as it will be in a few weeks but my knee felt well."
