Sir Alex Ferguson will give Darren Fletcher every chance to prove his fitness for the Champions League final on 28 May.
The Scotland midfielder has only played 20 minutes over the last couple of months because of a stomach virus that saw him lose more than a stone in weight.
Although Fletcher returned briefly against Schalke in the Champions League semi-final he is still some way off complete match fitness.
But with three games, against Blackburn and Blackpool in the Premier League and then Gary Neville's testimonial, before the clash with Barcelona, Fletcher will get a chance to show he is ready to feature at Wembley.
"Darren has put the weight back on and is back in training, but he has a bit to do yet. But, as far as the final is concerned, there is almost three weeks to achieve that," Ferguson said.
"If he does reach the target, it will be a big boost to us as we all know he is big-game player.
"The 20 minutes he got against Schalke last week was certainly a step forward. His training, in terms of sharpness for such an important game, will be stepped up now."
