Lingard was a revelation after linking up with his former boss David Moyes at West Ham in January for the remaining months of the campaign, and burst back into the England fold as a result.
Speaking to Sky Sports, Lingard outlined: "Regular football is the most important thing for me.
"After going on loan and getting a good run in the team, you started to see the real me, with the goals and the assists.
"I've never doubted my ability, I've always believed in myself. I spoke to the manager (Ole Gunnar Solskjaer) in pre-season and said, 'I need game time'.
"He said, 'we can discuss it December time', and we spoke again and he agreed to let me go on loan.
"I had various conversations with him during my time at West Ham. He was very supportive and it was a great loan for me."
