The Argentina international has been a mainstay of Mancini’s back four this season, and remarkably, the right-back has already scored three goals in all competitions.
And the 28-year-old reckons it is probably his standout season at the Eastlands outfit after completing a move to City from Espanyol in 2008.
“Probably, I think it is one of the best seasons for me since I signed for Manchester City.
“I am always trying to improve myself on everything but also I have to say I am playing with great players around me. That makes every player better.”
The South American was also pleased with City’s performance after Mancini’s men secured a rare victory at the Britannia Stadium.
“I think it was well deserved for the team. I think we did a great game,” he added.
“We knew it was going to be tough. It has always been a difficult pitch for us in the last few years.
“But I think we played a fantastic game. We were very solid at the back. We worked really well as a team.
“We created a lot of chances. I think it was the perfect game for us.”
