Now however, after the club overcame Anderlecht in extra time, Mourinho has claimed that he thinks Shaw has finally done enough to be trusted, and his mentality is now strong enough to impress his manager.
Mourinho said: “I always trust the players with special mentality. Always trust them. Luke Shaw did something new today, it means a lot for me.
“After 90 minutes, before I know that I have to change Zlatan, he had cramp, I had Ashley Young ready to come on, and he told me I’m going to play for 30 minutes with cramps, no problem.
“He said if you need to make a change in another position I am ready for it.”
United now face Spanish side Celta Vigo in the semi finals, and will come up against someone they know from his time at Liverpool – Iago Aspas, with the creative star on fire for Celta.
Getting to the final would be huge for Mourinho and his side, as not only will it potentially be a second trophy of the campaign, but it will also be a way into the Champions League.
