Manchester United coaching staff have been surprised by Luke Shaw's first week back with the club.
The Metro says Shaw has surprised Jose Mourinho and United's coaching staff by finishing top of early pre-season fitness tests.
The 22-year-old is entering the final year of his contract at Old Trafford and it's make or break time for the defender.
The left-back cut his summer plans short to train in Dubai with United's head of fitness and conditioning Gary Walker, a week before returning to pre-season.
Shaw stunned United's coaching staff by finishing top of all the pre-season fitness tests.
Shaw's fitness is something that's been criticised by Mourinho in the past and it appears he's actively trying to do something about it.
