Paul Pogba left the Emirates Stadium disappointed with national teammate Laurent Koscielny after the Manchester United star was sent off during the Red Devil's 3-1 victory over Arsenal on Saturday, 2 December, Jose Mourinho revealed.
Pogba saw a straight red card in the 74th minute of the game for a two-footed stamp on Hector Bellerin.
United still managed to secure the three points at Arsenal but the red card is a big blow for Mourinho's side with Pogba now set to miss the derby against Manchester City at Old Trafford on December 10.
The Frenchman will be available for the Champions League clash against CSKA Moscow on Tuesday night, 5 December, but he will then miss the visit of City and the following two Premier League games against Bournemouth and West Bromwich Albion.
Mourinho admitted that he was yet to see a replay on TV but the United boss suggested that Arsenal players, especially captain Koscielny, played a big part in referee Andre Marriner's decision.
"I just know Paul is frustrated and a bit disappointed with his colleague [Laurent] Koscielny for his reaction. But Paul was very frustrated. Everybody knows he is a clean player and it was not his intention, not at all, to be close to a red card. I've not seen a TV replay, so I don't know," Mourinho said following United's win over Arsenal.
"I don't know [if it was a red card]. I'll leave that one for you [the media]. I'll leave for you the Lukaku situation with [Laurent] Koscielny and I'll leave for you the Arsenal players on the grass, but I'll probably be the same because the grass is absolutely beautiful. I think there is a desire to go for the grass!"
Mourinho was still pleased with the performance of his side as United secured three crucial points to put pressure on City ahead of the leaders' clash with West Ham on Sunday, 3 December.
"I thought it was a phenomenal game. I loved the way my team played and fought. But I also have to say that Arsenal played, in some periods, amazing attacking football, creating difficulties for us. But I have to say that my players deserve all the great words. I don't know so many more in English! But amazing, phenomenal, fantastic, and deserved the three points," Mourinho added.
"The plan was when they [Arsenal] had the ball, we all had to defend, starting with the attacking players, and when we have the ball, we had to try to counter-attack fast and try to score goals, which we did. We had the ball against the post, we had this last situation with [Romelu] Lukaku facing Petr Cech and, of course, they [Arsenal] can say they had chances, but we fought and we had a great goalkeeper too and I think we deserve [the win]."
