Barcelona star Andres Iniesta is aware that Manchester City have enough quality to trouble them on Wednesday night.
The Catalan giants lead City 2-1 following the Champions League Round of 16 first leg in Manchester late last month and ahead of the return bout at Camp Nou, Iniesta knows that the visitors are capable of making life difficult.
"City have the kind of players who can turn this tie around," the midfield ace said.
"We have to go out with the same intentions as we did for the first leg and show that we are a team that is intent on qualifying for the next round.
"They have players, especially in attack, who can change a game at any time. We can't make the mistake of thinking that winning 2-1 in the first leg was enough.
"We need to control the game, get the ball rolling and make them run."
