Pogba finalised his move to Old Trafford on Monday afternoon and was officially announced by the club in the early hours of Tuesday morning.
Speaking about Mourinho’s business, Carrick claims all four of his new signings will be great for Man United.
“A transfer fee is a transfer fee,” he said.
“I don’t think that matters too much really. I think it’s more about getting the best players you can through the door and we’ve certainly done that this summer. All four players are going to be great for this club.
“Paul being the last one is massive news. It has gone on for a few weeks and I think he’s as delighted as much as anyone that it’s done now and he can focus on his football. I’ve said all along, since I’ve been here, the club needs the best players in the squad to push each other and challenge each other. Certainly, we’ve been given that this summer.”
Mourinho has done exceptionally well to complete all of his business early this summer and has successfully picked up all four of his fundamental signings before the club’s Premier League opener against Bournemouth.
His new acquisitions have plugged major gaps on the side and will play a vital role in his mission to get the club back to it’s former glory days.
The Portuguese boss has a big task ahead of him at Old Trafford, but it looks like he finally has everything in place to succed at the club this season.
