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."
Vidic added: "I knew I would be out for six months. I tried to make the best of it and when I came back wanted to be the same as I was before the injury.
"That was my target. We'll see how good a job I did in that six months."
Speculation continues about deals for Robin van Persie and Lucas Moura being close to conclusion.
Former United skipper Gary Neville, who arranged for a reserve team to visit Forest Green on Sunday as part of his Sustainability in Sport project, realises manager Sir Alex Ferguson, who did not travel to Norway, is eager to strengthen his squad, but that it will not be easy.
"The manager will always sign players he believes will develop into exceptional players," said Neville.
"There have been these stories about Lucas and no-one knows what is going to happen with Robin van Persie. It is always difficult to find the right players though.
"Manchester United already have an excellent squad who finished equal on points with the champions last year."
