Carrick's addition to the coaching staff isn't the only change at United, with assistant coach Rui Faria ending his 17-year partnership with Mourinho.
"I don't think about Moscow every day, but every time the Champions League comes on I get flashbacks".
Sergio Romero, standing in for United's player of the year David de Gea, who received the Premier League's Golden Glove before kick-off, saved in a De Gea-esque manner as he tipped an effort from Richarlison over after 44 minutes. "The only one was to try to break the 80 points barrier".
Speaking on the pitch after the game, Carrick said: "I would like to say thank you for your support over the years, I've got a lot of memories to cherish".
While Daley Blind and Matteo Darmian are already very likely to depart from Old Trafford, the arrival of Sandro could also push Luke Shaw out the exit door. "I think it will be Michael Carrick in the future when he has his badges".
"But in championships with 38 matches, the reality is always the reality of the numbers". The reality of the numbers is between second and fifth, the difference is three or four or five points but the difference between the first and second is a difference of 19. That's the reality of the numbers.
The Red Devils bounced back from their two games without a win against Brighton & Hove Albion and West Ham United to wrap their season up on a winning note.
United finish their 2017/18 campaign at Wembley next weekend, when they take on Chelsea in the FA Cup final, looking to secure their first silverware of the season. "Be happy, brother", he said.
"It wasn't the best [performance] from me [today] but it tells me the time is right".
However, both teams were wasteful in possession as the second half wore on which led to little action in either final third. The other way was "this is the position that is available and we are going for it".
It's an unbelievable opportunity to learn (from Jose Mourinho) who's been everywhere and won everywhere.
"We can disagree but he is still the manager and I am the player. We have had our ups and downs but we finished", stated Carrick.
