With Phil Jones and captain Nemanja Vidic still sidelined, Sir Alex is pleased to be welcoming Smalling back into the fold.
"Smalling has a chance to come back - Jones and Vidic, obviously not," Sir Alex told Sky Sports. "Ashley Young will start training while the internationals are on, particularly in the second week.
"At a stretch Young could maybe make the game against Stoke but, certainly Smalling, he will have done enough training on the football side [for this weekend]. Particularly as we have had a problem with centre-backs, that is a blessing for us."
