Warne prepared for his side's 7-0 FA Cup mauling at Manchester City by meeting a potential target for a coffee on Saturday and reported that the player told him he wanted to join.
De Bruyne was a key player in the side that won the title last term, but injuries have restricted him to six league appearances resulting in City being nine points worse off than they were at the same stage last season. "Without him, last season maybe it would not have been possible".
"He played incredible, created a good amount of chances and has a vision that others aren't able to see. We have an opponent [Liverpool] that has done better than us, without us having him, and that can happen".
However, youngster Phil Foden made it 2-0 for Man City two minutes before the break with a scuffed effort inside the box against the run of play.
City, who trail league leaders Liverpool by four points, next host Burton Albion in the semi-finals of the League Cup on Wednesday before facing Wolverhampton Wanderers in the Premier League on Jan 14.
"It's another 90 minutes for his experience and his self-confidence".
Foden admitted his goal was lucky but was delighted to score at the Etihad after his first goal earlier in the season in the cup win over Oxford United.
"He text me within an hour saying he would really want to come".
In the 73rd minute, Riyad Mahrez made it five for the Citizens after finishing off a slick passing move that involved Oleksandr Zinchenko and Ilkay Gundogan. "I'm getting a lot of games and enjoying it a lot".More news: Disneyland Announces Ticket Price Hikes Ahead of New Star Wars Land Opening
