MIAMI -- Manchester United trio Eric Bailly, Ander Herrera and Chris Smalling have missed training ahead of the clash with Real Madrid.
Luke Shaw was part of the group which trained at Barry University on Monday morning despite missing the defeat to Liverpool in Michigan on Saturday.
Sources have told ESPN FC that Herrera picked up an ankle knock during the 4-1 defeat to Liverpool in Ann Arbor on Saturday, while Bailly suffered a similar problem during the victory over AC Milan in Los Angeles last week.
Jose Mourinho will now have to decide whether to risk the pair against the Champions League holders with just 10 days to go before the start of the Premier League season.
