New Manchester United manager Jose Mourinho already wanted to move to Old Trafford in 2010, Chelsea legend Marcel Desailly said.
The Portuguese signed a three-year contract with the club and will earn £10million a year according to reports in England.
And Desailly says he is expected to spend €250million to strengthen the squad this summer.
"I was in Mexico with him at a FIFA conference,'' Desailly told ESPN.
"Remember, when he left Inter Milan to go to Real Madrid [in 2010]?
"At the time, he said he would come back to England. But his plan was to go to Manchester United, not Chelsea.
"This was his main target. He respected the club. The worldwide exposure is through Manchester United.
"Now, he has got the key from them. The other one [Louis van Gaal] spent €200 million. He will spend another €250m, also. And he'll build up something good, I'm sure.
"He has some problems because he has Juan Mata, who he didn't want at Chelsea.
"I'm sure [Marouane] Fellaini won't be playing in midfield. He has a lot of things to work on."
