Tuchel expresses dissatisfaction with Mainoo's training during World Cup buildup

England manager Thomas Tuchel was not pleased with Kobbie Mainoo's performance during training ahead of the World Cup group match against Ghana. Mainoo, an unused midfielder for Manchester United, was expected to play due to Declan Rice's injury concerns. Tuchel's tactical decisions have come under scrutiny following England's recent defeat to Argentina in the World Cup semi-finals. Some players reportedly feel that the substitutions made by Tuchel did not benefit the team during that match. There are ongoing discussions about England's strategy as they prepare for upcoming matches.
