McTominay, who turns 23 on Sunday, revealed to MUTV that he was chomping at the bit to be involved against Spurs, following a three-game spell on the sidelines.
“I was desperate to be on the pitch - it was disappointing to watch those three games," he said.
“The atmosphere was brilliant tonight. Some of the skills and tricks in the first half, and in the second half, were absolutely scintillating and it was a pleasure to be a part of it."
When questioned on how he felt after the game, McTominay revealed he was in fine fettle.
“I try to look after myself as best I can. I trained yesterday for the first time and played today, so I feel good. I'm only 22, so I should be fine."
