Carrick will move into Mourinho's backroom team from next season and the Portuguese added: "It was already hard for me because I got him in the last two years of his career".
"I will organise my staff in a system where an assistant manager doesn't exist".
"I think it will be Michael Carrick in the future, when he has his badges, his pro licence, when he makes the bridge between a player to an assistant", said Mourinho.
"I'm going to bring some people in that until this moment you (the press) didn't come up with the name yet".
And it was the former England midfielder who made the decisive contribution, his superb lifted throughball enabling Juan Mata to tee up Marcus Rashford to break the deadlock.
"I think if you're looking at the City game now..."
"I have had 17 years of incredible and unforgettable experiences". Some have always been waiting for this and have come to terms with selling him, but some are still angry to see such a talented player be wasted by Mourinho.
"[Martial's injured]. He was injured in Friday's training session, yesterday couldn't train", Mourinho told reporters. "He had treatment in the morning at the training ground and then stayed away".
"Romelu will be back for Tuesday so we'll see, but Anthony, I have to wait a bit more", said Jose Mourinho.
'I'm waiting for the doctor but when it's impossible to play today, I have my doubts (for the Cup final)'.
"I'm sure the owner will try to improve the level of the squad and the team, try to improve the position in the table".
