The Croation spent a year at Eastlands before moving to White Hart Lane on the same day City were bought by the Abu Dhabi United Group.
But although City are now the richest club in the world, Corluka insists he has no regrets about jumping ship.

Corlukaclaimed when he joined Spurs that they were a bigger club than City - and he has seen no reason to change his mind.
'I still think that,' he said. 'The fans are a little bit more close to the club here than at City. I have nothing against City and I had a great time there but when I played for City, the stadium wasn't always full, whereas here, you never see that.
'Here, the stadium is full even when we play friendlies, so you can see that there is more passion for the club here than there is there. The most important thing for Spurs now, though, is to keep this team together and to add some players, not to sell two players and then try to rebuild the team because then it's a hard thing to do.'
'When you have a squad that have been here for a while and you just bring in the players you need - the manager will know them - then it's much easier. If we stay together for a long time it's easier to achieve bigger things because we will know each other so well.
'Everyone wants to play in the best competitions but we need to try to achieve that here, not think about leaving the club to go somewhere else,' added Corluka. 'We need to try to put the club in the Champions League next year.

'I'm good friends with Luka [Modric] and I don't see any desire there that he wants to leave the club. When I have spoken with him, he has never said that he wants to leave Spurs. He knows he is an important player here, everyone likes him and I think he wants to achieve good things.
'But, of course, he will expect maybe a couple more signings to be added to this team. I have known him since he was 14, and even then you could see he was a quality player but now he's showing it in one of the toughest leagues and you see that he is probably one of the best in his position.'
Corluka has struggled with injuries to both ankles this season that left him unable to play more than once a week.
But he remains Harry Redknapp's first-choice right back and is confident that Spurs can fight it out at the top of the table next season.

'As for next season, it's difficult, but with some investment, of course, we could be there to compete,' Corluka added.
'It's hard to say we can win the league in a certain period, though. We need to think positively and to think we can do it but when, we don't know.'
Vedran Corluka was speaking at an event organised by Tottenham sponsor Autonomy, which allowed young supporters of the Arthur Rank Hospice Charity, based in Cambridge, to play at White Hart Lane.
