The Man City winger revealed that he turned down a move to arch rivals Celtic in favour of moving to Ibrox on a season long loan.
He told Rangers TV: “As soon as I got this offer I was really interested.
“I had a few offers, including from Italy and Germany, and then the offer from Rangers came and to play for a big team like this will be a pleasure for me.
“I aim to do my best and hopefully we will have a good season.
“Celtic came in for me first but then Rangers came in and when I looked through all of the offers that I had, I picked Rangers.
“The fact that Rangers are in the Champions League was obviously a big incentive for me. Every player wants to play in the Champions League so it’s a great opportunity for me.
“I hope we get an interesting group and that we do really well.”
