Mourinho: Why I had to take Fellaini off

The Belgian midfielder lasted only seven minutes after coming on with Juan Mata as part of a double change for Jesse Lingard and Paul Pogba, during the second half of the disappointing 2-0 defeat at Wembley.

"I think I was unlucky with Fellaini as I wanted to change a little bit the dynamic of the team," the boss told BT Sport. "After a couple of minutes, he was injured. It’s always the same thing. It is the lateral ligament. I don’t think it’s a big, big thing but he was immediately feeling something and telling us he couldn’t carry on."

Fellaini must now be considered a doubt for Saturday's visit of Huddersfield Town to Old Trafford as the Reds look to get back on track by avenging the surprise defeat at the John Smith's Stadium earlier in the season.

The manager also suggested in his post-match press conference that it is the third time the midfielder has been hampered by the issue with his knee and former Reds defender Gary Pallister added on MUTV: "It's frustrating for the lad. He gets himself back but they haven't been able to get to the root of the problem and they may need to take another direction with it.".
