Ruben Amorim wants his Manchester United players to fight each other if they lose the ball, just as Everton did en route to getting a red card in their win at Old Trafford.
United looked set to cruise through the game when Idrissa Gueye was shown a straight red card for slapping Michael Keane inside the first 15 minutes.
But United never looked remotely in control as they produced arguably the worst Premier League performance in Amorim's year in charge.
Amorim not only disagreed with the red card shown to Gueye - who apologised in the dressing room after the win - he wants to see his players do exactly the same in future.
