The Manchester Evening News goes on to claim that Mourinho even went as far as asking Croatian legends Mijatovic and Suker for their opinions on the 29-year-old winger.
Shaw started eight Premier League games last season, ultimately costing him a place with England for the World Cup, and he has started just 17 of 76 league games since Mourinho became manager in 2016. So many players didn't have the opportunity to win and help their team enough.
"That's the point about his performance level and contribution to a winning team: it is to understand why he was so good especially in the second part of the competition, where he was absolutely brilliant".

If Sanchez fails to secure entry to the US, United have a friendly at Bayern Munich on August 5 before their league opener against Leicester City at Old Trafford on August 10. "I'm looking forward to a nice pre-season, we've got our first training session at UCLA so it should be fun", the 35-year-old ex-Stoke keeper told MUTV.
"The club, manager, and team always receive a great welcome when visiting America, with our millions of U.S. fans always keen to get closer to Manchester United".
"Dalot is injured", Mourinho added.
