The Serbian International joined Roberto Mancini’s side for £19 million last summer and managed 37 appearances in his first year at Eastlands scoring three times.
Kolarov was a crucial part of the team that secured the Citizens first piece of silverware in 35 years as City defeated Stoke to win the FA Cup.
The left-back admits he was flattered by the attention of Real and Inter but is fully focused on helping Roberto Mancini’s side progress in their first Champions League campaign and to improve on their third place finish in the Premier League.
He told Sportske: "I really can't say that I regret that I signed for City.
"It is true, Real and Inter were interested in me, but City showed the biggest will and wish to sign me.
"They told me immediately about their big ambitions, they explained to me that they want to be the best club in England in the next two years, and of course, that matched my ambitions.
"Real and Inter are great clubs that I truly respect but I play for such a great club. I'm really happy at City."
