Apparently chose United over City:
"I signed for United because I like Mourinho, as simple as that. “I wanted to play for someone who works very hard. I didn’t speak to Pep Guardiola but the ‘second’ manager called me and Mourinho called me as well. “He said come and play for me. I prefer Mourinho, in part because of Didier Drogba, who Mourinho worked with. “I have played with Didier in the Ivory Coast, he is a friend and he told me, ‘Jose did this for me, Jose did that for me’. “Yaya also called me and said come to City. But once Jose spoke to me and Didier gave me advice, I knew straight away I wanted to play for him.”
