It means United are out of both Cup competitions and also Europe for the remainder of the season.
Fletcher said after their third round defeat: “We’re out of the cups and only Premier League games to play for. Fans weren’t happy at the end but they’ve got every right to air their grievances and I don’t think it was toxic by any stretch of the imagination, so they showed their disappointment and they have every right to do that.
"The fans have supported the team for a long, long time and got behind them. Old Trafford is an amazing atmosphere. They went out of the cup today so understandably they are disappointed but I’m sure if the players show the right reaction, the fans will get behind them like they always do because, as I said, there’s still a lot to play for in the Premier League this season.”
Asked if he believes he will be replaced by a more permanent appointment this week, Fletcher also said: “This is what I’ve been asked to do so I’ve not had any discussions beyond that. I’ve done the job this week and we have had to concentrate on the game. All the discussions beyond that will, I’m sure, unfold in the next couple of days.”
Meanwhile, Fletcher had a word for Shea Lacey, who was sent off late on.
He added, “He’s disappointed because he cares and he understands. He knows he will learn from it. There’s no doubt about his talent and it’s a steep learning curve today but we believe in Shea, he’s one of our most exciting young prospects. I’m sure at Old Trafford he will have a chance to make amends for that in the future.”
