And just two nights before the fixture, Man Utd’s Under-21 side drew 1-1 with Fulham.

But many supporters noticed that Mainoo was not in the the squad for the clash.

This comes after he had started their previous game on Tuesday, which was a 1-0 Youth Champions League defeat to Copenhagen.

It was the 18-year-old’s first appearance since hobbling off injured due to an ankle issue in a pre-season encounter with Real Madrid in July.

He has been back in training for several weeks and fans believe he might have finally made a full recovery as he eyes more first-team opportunities.

One supporter said: “No Mainoo. He is about to cook City.”

Another added: “Mainoo not here meaning he could be involved in the Manchester derby.”

More reacted: “No Mainoo, haha City watch out.”

A fourth wondered: “Mainoo not there interesting…”

There could be a spot for the midfielder amid some doubt over the fitness of Casemiro as he continues to nurse a minor ankle problem.

Meanwhile, Erik ten Hag already has Lisandro Martinez, Tyrell Malacia, Luke Shaw, Aaron Wan-Bissaka and Amad Diallo all sidelined.
