Jose Mourinho branded Marcus Rashford "a naive boy" after he was sent off in Manchester United's win at Burnley on Sunday.
England forward Rashford was given a straight red card 71 minutes in for pushing his head into Phil Bardsley, whose kick out at the 20-year-old had gone unseen by referee Jon Moss.
The dismissal did not prove costly to the visitors at Turf Moor, though, as United saw out the victory given to them by Romelu Lukaku's first-half double.
Mourinho felt Rashford was to blame for being provoked by former United man Bardsley, but he was nonetheless thrilled with his side's display.
