Wayne Rooney has recovered from the knee injury he suffered at Anfield on Saturday and will be fit for United's Champions League clash against Lille on Wednesday.
United are a goal to the good in their last 16 tie thanks to Ryan Giggs' much-disputed late goal in Lens two weeks ago, but there had been some as to whether Rooney would be fit for the second leg clash at Old Trafford.
The Reds' striker came off worse following a collision with Liverpool defender Jamie Carragher which left Rooney with a large gash just above his knee, which required eight stitches.
He was replaced soon by John O'Shea, who went on to be United's goalscoring hero in the game with an injury-time winner in front of the Kop.
Rooney had a scan after the match but Sir Alex Ferguson has since confirmed the 21-year-old is available to play against Lille.
"Wayne will be okay for Wednesday," the boss told ManUtd.com. "We have a couple of doubts but Wayne is not one of them."
Elsewhere, Paul Scholes is available despite being suspended domestically, but the 32-year-old is one yellow card away from a European ban, as is Patrice Evra.
