Roy Keane and Graeme Souness both questioned Anthony Martial's emotional commitment to football, and said they believe the Frenchman has the talent but lacks the desire to be a top-class player.
Both pundits were speaking in the aftermath of Manchester United's 0-0 draw with Chelsea on Sunday, one of the Red Devil's biggest games with regard to the Premier League title race and Champions League qualification.
Martial, 25, was omitted from the starting line-up despite forward Edinson Cavani being injured. Marcus Rashford, Mason Greenwood and Daniel James began the game, with Martial coming on with 11 minutes to go.
