Graeme Souness has defended Thomas Tuchel's decision not to use Kobbie Mainoo during England's World Cup semi-final defeat to Argentina, arguing that the Manchester United midfielder still lacks a clearly defined role. In Souness's view, that uncertainty can become a major issue in a high-stakes knockout match.

The former midfielder said his concern is largely about shape and control in the center of the pitch. He suggested Mainoo can leave areas in midfield too easily, which may weaken a team's structure when a manager is looking for discipline and balance rather than risk.

Souness used that argument to explain why Tuchel may have trusted other options instead of turning to Mainoo as England exited the tournament. His defense of the selection focused on tactical demands and positional responsibility, rather than club status or the player's overall promise.

He also dismissed the idea that his criticism reflects any bias against Manchester United or against Mainoo personally. Instead, Souness presented his view as a football judgment on how the youngster fits into England's midfield, a debate that is likely to continue after the World Cup setback.
