Manchester United's Anthony Martial was involved in a training ground disagreement at Carrington last week. Martial has not made France's squad for the World Cup and he's remained in Manchester to train with the players left behind.
The Manchester Evening News understands Martial was tackled in training last week by 18-year-old Daniel Gore and the pair were involved in a minor squabble, but that both players quickly made up and the incident has been played down.
It's also understood that tackling first-team players with Erik ten Hag in charge is actually permitted in training, contrary to reports.
