The Englishman, who enjoyed his first run of games in the senior side back in October 2015, has made 42 appearances under the 54-year-old.
Lingard’s unyielding commitment to the cause culminated in the 24-year-old being offered a new four year deal worth £100,000 back in early April.
And the winger, speaking on Sky Sports, noted that earning the manager’s trust has been crucial to his progression this season.
“It’s good that the manager trusts me. I played in a lot of different positions, and obviously to play in the final as well was massive,” he said.
“Each day you’re learning from the manager about game management. There are things he wants you to do on the pitch, especially if you’re winning games, so you’re always learning.
“We were sixth this year, but we’re still in the Champions League. Next year we’ll concentrate on the Premier League.”
Lingard, now with 83 Man United appearances under his belt, has established himself as a reliable pair of hands at Old Trafford – as somebody capable of maintaining a quick tempo, acting more often than not as an important intermediary aspect of attacking movements instead of being the end product.
But as Mourinho looks to take his side to the next level over the summer, most likely with the aid of additions to the attacking frontier, you sense that Lingard will need to improve his potency in front of goal to keep such a regular place in the starting XI.
