Louis van Gaal's side were very disappointing during the first-half at Anfield.
Morgan Schneiderlin has explained that Manchester United's disappointing first-half display during their clash with bitter rivals Liverpool led to a heated exchange between the players at the break, the Daily Star reports.
The Red Devils were disappointing during the first 45 minutes at Anfield, and the Frenchman explained that the frustrations boiled over once they returned to the dressing room.
In the first half, we didn't win enough second balls. Sometimes we won the first ball but not the second ball.
"When we came into the dressing room after the first half, there was some screaming and shouting, but of course that is normal because in a derby you cannot lose the battle," he said, as reported by the Star.
The exchange between the players seemed to do the trick somewhat, as a late Wayne Rooney goal saw Louis van Gaal's men take all three points, sending them fifth in the Premier League table, just two points off the top four.
Despite the victory, the performance was still arguably unconvincing. Jurgen Klopp's side had 12 more attempts than United, while Rooney's strike was their only shot on target during the entire game.
While the style of play that United have adopted under van Gaal continues to come in for criticism, the Dutchman will be pleased that his side are often managing to grind out victories in matches when they are struggling to dictate the game.
