On Thursday, the club announced that Shaw had signed a new deal to keep him at Old Trafford until 2023, capping a remarkable turnaround that has seen the 23-year-old go from forgotten man to first-team regular.
"Luke fully deserves this contract," Mourinho told the club website. "He understood his development process, he has worked really hard at every level and he always believes in himself which is a great attribute to have.
"Luke is still young and is improving all the time and he must feel very proud of himself.
"I am delighted that we are keeping such a talented young English player with a bright future ahead of him."
