Old Trafford felt different on February 7, 2026. The anxiety that plagued Manchester United under Ruben Amorim had vanished. In its place: confidence, creativity, and a 20-year-old midfielder who is suddenly indispensable.

Manchester United defeated Tottenham Hotspur 2-0. It was their fourth consecutive Premier League victory under manager Michael Carrick. They sit in fourth place. Three months ago, this seemed impossible.

The Tactical Shift

Carrick changed everything. He abandoned Amorim's three-at-the-back system. He installed a four-man defense. And he brought Kobbie Mainoo back from the wilderness.

Mainoo had been marginalized under Amorim. He has played more Premier League minutes for Carrick in one month than he did for Amorim in four.

'There's no doubt about Kobbie's ability and what he can bring,' Carrick said. 'He's still so young and learning the game.'

The Decisive Pass

United's first goal came in the 38th minute. First-team coach Jonny Evans devised a short-corner routine. Mainoo executed it perfectly.

The 20-year-old made a 'perfectly timed run' from the front post. Then he delivered a 'no-look, over-the-shoulder pass to Bryan Mbeumo' that GOAL.com described as 'pinpoint.'

The goal changed the game. Cristian Romero's red card four minutes later made it easier. But Mainoo's pass opened the door.

The Second Strike

Bruno Fernandes sealed the victory after halftime. His goal came from a Diogo Dalot cross that Mainoo had delicately flicked into his path.

Two goals. Two Mainoo contributions.

This is the same player who was being linked to Napoli transfers under Amorim. Now he is untouchable.

The England Question

Mainoo also registered an assist in the 3-2 win at Arsenal last week. His form has raised a tantalizing question: Could he make England's World Cup squad?

Thomas Tuchel will name his squad in March. If Mainoo continues at this level, he will be impossible to ignore. It is less than two years since the teenager started in the European Championship final.

United have kept three clean sheets in four games under Carrick. They are playing with swagger again.

The revival is real. And Kobbie Mainoo is at the center of it.
