Jose Mourinho has explained exactly why Manchester United midfield have not been good enough this season.
The Red Devils have struggled this term and are currently seventh in the Premier League, 14 points behind leaders and rivals Manchester City.
United also has a minus-one goal difference, having struggled to both score and defend at times this season.
Saturday's draw against Crystal Palace almost demonstrated both of those things. United were unable to threat the visitors at Old Trafford and were lucky to be behind on more than one occasion.
Mourinho believes the weakness lies between attack and defense.
Paul Pogba and Nemanja Matic have played the majority of United's games and Mourinho has a message for them.
Speaking in Monday's press conference, prior to Tuesday's Champions League clash against Young Boys, he explained: "Our midfield is not aggressive in the fight for second balls."
"I refuse to say that because I do not want to disrespect the home fans.
"I prefer always play to home. If you feel pressure, stay at home … and I do not mean stadium home, I mean home home!"
United have the chance to progress into the last-16 on Tuesday evening. If Juventus and the Red Devils both win then Mourinho's men will find themselves in the knockout stage of the competition.
And turning his attention to the Champions League tie, he said: "Tomorrow is not vital because even if we lose we depend on nobody but ourselves.
"But I want to play from one minute to the next, we have to qualify. We have to win, that's the way I want to play."
