Sir Alex Ferguson has revealed that Darren Fletcher will not start on Sunday against Chelsea, as the Scot continues to recover from a virus that has sidelined him for 12 weeks.
"The 20 minutes will have given him a boost," Ferguson said of Fletcher's time on the pitch against Schalke on Wednesday.
"It's a step forward, but the boy's got a bit to do yet.
"He won't start on Sunday but his training will be stepped up in terms of the sharpness needed for such an important game ahead."
The Manchester United midfielder contracted a virus three months ago, and while he has recovered, Fletcher lost over 10 kilos and is still training to be match fit again.
As Manchester United take on Chelsea on Sunday, the title is on the line for the Reds, with United just three points ahead of the Blues on the Barclays Premier League table.
Ferguson insists that Fletcher will have some part in the lead up to the end of the season, even if it is just of the Champions League variety.
"As far as the final's concerned, he's got almost three weeks. That's his target and hopefully if he reaches it then it will be a great boost to us because, as we all know, he's a big-game player," Ferguson said.
"We've also got Blackburn away, Blackpoool at home, even Gary Neville's testimonial game... so there's opportuity for game time that will help him reach his target."
