United boss Amorim explained earlier this month why he has not been providing Mainoo with more game time, telling reporters: "We need to go to Europe because of everything. Our club needs to be in Europe, it’s hard to have a very, very good squad. Imagine for me to have Mainoo with that (many) minutes that he’s playing, he needs more games for me to make a rotation because, with one game (a week), it’s really hard. I have to take one of the guys that is playing to put another. When you have more games, you can divide, you can manage the group in a different way. We are trying to use the time that we have to train to be a better team, we need to be prepared in the future to have European games. But the target doesn’t change. We have to go to Europe. To be in the top four is really hard for our moment, but we never know, we just need to focus on winning the next one."
Mainoo will hope to feature when United take on Everton in the Premier League this weekend.
