One man that was heavily linked with Man United in the final days of the transfer window was World Cup victor, Jerome Boateng.
After identifying Toby Alderweireld as his top choice, Mourinho then moved on to the likes of Boateng, Harry Maguire, Yerry Mina, Diego Godin and Kurt Zouma.
But a deal was never completed between United and Bayern Munich.
Another defender who was strongly linked with a move to Old Trafford was Germany and Bayern Munich defender Jerome Boateng.
"As a fan, honestly, part of me says that no one is bigger than the club and I am not interested in people who are looking left and right". It was no escape, but rather the thrill of a new challenge.
"I phoned Jose Mourinho and told him that his interest honoured me and thanked him [for trying so hard to try and bring me to United]. Everything has to fall in place to top this club, if I do it. Niko Kovac gave me the feeling that I am very important for him and the club".
So there we have it.
Tottenham were heavily linked with the player throughout the summer, while Chelsea were also said to be keen.
"That's not true. This summer, I quickly understood Tottenham wanted to keep me".
"They have to protect their asset but privately they might be doing a deal because they want to get their £90 million back". But, his place in the Bianconeri's first-team setup seems to be in jeopardy for the first time in over three years following the arrival of Cristiano Ronaldo.
