Multiple outlets’ newspaper round-ups report that Chelsea manager Thomas Tuchel is unhappy with Manchester United midfielder/“Mainoo” regarding his training during the World Cup period. The stories describe the issue as dissatisfaction over how Mainoo has trained during the tournament timeframe, though they do not provide further detail in the material provided about specific sessions, reasons, or consequences.

Across the sources, the central point is consistent: Tuchel’s view of Mainoo’s training during the World Cup is negative, and this has become a topic in the press. The round-ups are also presented as containing broader football headlines and transfer rumours, but the only confirmed overlapping element across the excerpts is the claim about Tuchel’s dissatisfaction with Mainoo’s training.

No additional reporting on actions taken—such as changes to training, selection decisions, or any formal disciplinary steps—is included in the provided summaries. The information is therefore limited to the reported complaint and its presence in the newspaper stories.
