Outgoing Borussia Dortmund defender Mats Hummels claims Ilkay Gundogan made no secret of his desire leave Signal Iduna Park and join Manchester City.
Gundogan remained hot property despite struggling with a slew of injuries this past season and the completed deal between BVB and City was announced on Thursday.
It is the Citizens' first major transfer of the off-season and is reported to be in the region of £20 million.
"We all knew for some time that this is what he wanted," Hummels told reporters. "I am happy for him that it worked out now, because he decided that he wants to do it and his injury kind of questioned this again.
"So I hope for him that he made a good decision and especially that he will be fit again soon. Because if you're not fit it doesn't matter where you are: You won't play anyway."
Midfielder Julian Weigl conceded Gundogan's departure would be a big loss for Dortmund, but is confident the club will be able to make do without him.
"Of course Ilkay was a really important team member. I played pretty well with him next to me. It fitted really well," Weigl said. "So of course it's a loss to our team. But we knew for quite some time that he thought about moving to another club.
"We played well without him as well. But it is sad that he has taken this path. Everybody needs to make his own choices. He wants to make the next step. Dortmund will be prepared I hope."
