Former Manchester United captain Roy Keane launched a scathing attack on Mourinho following his comments and questioned whether the Portuguese is up to the demands of the job.
That means, from April 1, the Red Devils are scheduled to play NINE times before the end of the month.
Keane said: "Why do we have to listen to that garbage?"
"I just think that it needs a little bit of common sense".
Manchester United manager Jose Mourinho says wants to stay at the club for "many years", but laments the fact he is treated in a different manner by football authorities to his rival managers.
But I am going to go for Man Utd, who I think will just have too much pace for them and I think they will just win this one 2-1. They've had an easy way in the cups, some good draws, a lot of home draws, and the guy is talking absolute nonsense. The Swede has 15 goals in the Premier League this season; nine more than any other player for the club (Juan Mata - six goals).
Man United have never won the competition in their history but it could be their saving grace as they seek a return to the Champions League as well as handling Zlatan Ibrahimovic his first silverware in Europe.More news: Kim Jong-Nam's killing a 'US plot', North Korea claims

Manchester United are unbeaten in eight league meetings since a 4-1 defeat on Teesside in October 2005 (W5, D3).
But Mourinho lost two key players to injury in defender Daley Blind and world record signing Paul Pogba, and went on the attack after the game in an interview with BT Sport.
"I still think we can win a lot of games and get into the third or fourth positions", he said. We will probably lose the game on Sunday. Marcos Rojo was so depleted of energy during the game that he called for a banana to be brought on to the pitch. The manager defended his expensive player but he really needs to start justifying his 89 million pounds price tag by scoring more goals and playing more consistently for his team.
Man United will play Belgian side Anderlecht in the quarter-finals of the Europa League.
Manchester United will have to look to keep Teodorczyk of the scoresheet. "I am saying this for many, many years".
However, fellow strikers Anthony Martial and Wayne Rooney are both injured as United try to take another step towards winning the Europa League and qualify for next season's Champions League.
United are bidding to become the first team in Premier League history to claim their 600th victory in the division, a result which would see them maintain their top-four bid.
