Barcelona ace Andres Iniesta says keeping Alexis Sanchez quiet is key to beating Champions League opponents Arsenal.

Iniesta insists his former team-mate will get a great reception from Nou Camp fans.

He said: “Arsenal have a big squad but, because of his history with Barcelona, Alexis is the key man we have to look out for.

"He's a big footballer and showed his level when he played for Barca. But it's not easy at this club to be first-choice striker. He has a lot of quality and can create problems.

“I'm convinced our fans will give him a great reception. But from minute one on the pitch, it will be different. That's logical."
