Ten Hag said: "To go to the final we have to win against Coventry, we will have to play at our best. We saw that Coventry have great spirit, a great mentality. We will prepare our best to play in the final.
"The first 30 minutes was the best of our whole season, we were acting as a team but then we got gaps between the lines and you can't allow this against one of the best teams in Europe. They outplayed us.
"Then we made changes, we took risks and the players were wonderful. The attitude was great, a strong belief to win this game.
"Rashford is resilient, he keeps going, normally he finishes those moments but he kept going for another chance. That inspired the other players.
"We have a team that is for the future. Coming up are players who are developing very well like Diallo, Garnacho, Kobbie Mainoo."
