Former Chelsea and Nigeria midfielder John Obi Mikel has launched a strong defence of Kobbie Mainoo while pointing the finger at Manchester United manager Ruben Amorim. Speaking on the Obi One Podcast, Mikel argued that Amorim has stripped the midfielder of his confidence, leaving him looking a “shadow” of the talent that burst onto the Premier League scene last year.
John Obi Mikel claims Ruben Amorim has turned one Man United player into a ‘shadow’ of his former self — captures the frustration surrounding United’s faltering season. The Red Devils slipped to a 3-1 defeat against Brentford at Old Trafford, their third league loss of the campaign, leaving Amorim under mounting pressure.

While Bruno Fernandes drew criticism from fans after missing a crucial penalty, Mikel singled out Mainoo as the bigger concern. The 19-year-old was once touted as United’s midfield cornerstone for the future, but his performance against Brentford reflected a player lacking clarity, rhythm and belief.
“And again, I watched this kid, Kobbie Mainoo. My word. What has happened to Kobbie Mainoo? What has happened to that kid?” Mikel asked. “A shadow of who he was when he burst onto the scene. He looked heavy. He looked like he doesn’t know what he’s doing. And when the manager doesn’t believe in you, when the manager doesn’t have the belief and trust, that happens.”

Mainoo’s struggles under Amorim
Mainoo came off the bench in the 66th minute against Brentford, replacing Manuel Ugarte. However, he failed to provide the control or spark United desperately needed. Instead, Brentford capitalised on gaps in midfield to score decisive goals.
Concerns over his development are growing, especially with reports from TBR Football suggesting Mainoo could be open to leaving Old Trafford after contract talks stalled. For United, losing another academy gem would be a painful blow.

The numbers underline Mikel’s assessment: solid passing but little influence on possession or defensive solidity.
Analyst verdict – John William
FootballPlace analyst John William believes Mainoo’s dip reflects a wider issue at Old Trafford. “United look like a team caught between systems. Amorim hasn’t found the right role for Mainoo, and a player who should be thriving is now stagnating. Mikel’s comments reflect what many fans are seeing — a kid stripped of confidence.”
He added: “The talent is still there. The challenge is whether United can stabilise quickly enough to protect Mainoo’s development, or risk losing him like other academy graduates.”

This United squad doenst need another coach that plays his system. Even though Glasner has been linked with a move, they need someone who utilize the players so Bruno at a 10 position. This means, they will need to play more in a 4231 system. Unless you get rid of Bruno
