Vidic is now looking forward to next week's meeting with Barcelona in Gothenburg as the Reds' pre-season preparations continue.
He told MUTV: "It [Barcelona] will be a tough game, but obviously it will be a good test for us. We need those games before the league starts. We have to know it's a friendly game and it doesn't count for the trophies and points.
"Last year we beat Barcelona in a friendly game and lost in a final, and hopefully it will be a good test and we will have a good game, but we have to prepare for the Premier League and Champions League. This is our target."
