Antonio Valencia is set to return to the Manchester United squad for Saturday's FA Cup quarter-final clash against Arsenal.
The Ecuadorian winger has been training for three weeks after suffering a dislocated ankle in a challenge with Rangers defender Kirk Broadfoot in September.

“He came close to being involved at Anfield but he will definitely play some part against Arsenal,” a United source told Goal.com UK.
“It is a big boost for the run in to have him back – but he will need to build up his fitness.”
United boss Sir Alex Ferguson will welcome the midfielder's timely return this weekend after losing Nani to injury in the 3-1 defeat to Liverpool.
Nani, 24, is still being assessed by club medical staff following a deep gash sustained at Anfield after a reckless tackle from Jamie Carragher that left Ferguson furious.
United expect to be without the Portuguese winger for at least two weeks but expect to have to wait at least 24 hours before they can make a full prognosis.
In the meantime, Ferguson will hope Valencia can immediately find the form that made him so popular with the fans last season following his £16 million move from Wigan.
Valencia was originally expected to miss the rest of the season after sustaining the horror injury but recovered ahead of schedule thanks to a revolutionary underwater treadmill designed by NASA.
Park Ji-Sung is also on the verge of returning from a hamstring injury that has kept him out for a month as United prepare for an anxious run-in.
