Man Utd play FC Twente in the Europa League on Wednesday and they will prepare by training on Tuesday.
Journalists are invited to watch a segment of training ahead of European fixtures and it's an opportunity to see which players will make the squad for the game on the next day.
There are different levels of calf strains but muscle fibres can heal in the space of four weeks if a tear isn't serious. The severity of Shaw's problem wasn't revealed by a club source when his injury was confirmed but it wouldn't be a shock to see him present in training on Tuesday. "But you're always dependent on how the progress will go and you can't think, you can't make a suggestion because there are so many factors, a plan can accelerate or slow down."
United have kept more clean sheets in their last six Premier League matches than they did in their previous 24 and the current back line have started three successive games together.
