City brushed aside the Hammers in the first leg at the Etihad with a convincing 6-0 victory to all but book their place in the Final at Wembley in March and keep their quadruple hopes well and truly alive.
But the Argentine right-back has vowed to take the second leg seriously and reiterated that the Citizens will approach it like any other game they have played this season.
“It doesn’t matter about the first leg. We have to go into the game thinking it’s a new game, even though we have six goals,” he told City’s official website.
“We need to try and win it, like we are doing at the moment. We are winning games and working hard.
“West Ham are in a tough moment, they are at home and will want to win it. So we need to take it seriously and we will.”
An Alvaro Negredo hat-trick helped City towards their record breaking semi-final victory over the Hammers two weeks ago, with Edin Dzeko and Yaya Toure also getting on the score sheet at the Etihad.
