AC Milan coach Massimiliano Allegri has admitted that his side must be alert to the threat of Andres Iniesta in the Champions League last-16 match against Barcelona on Wednesday night.

Allegri said that Lionel Messi was a huge threat but his side must equally concentrate on the passing ability of Iniesta.

"Messi makes a big difference, but the Barca threat is not only him," ANSA quotes Iniesta as saying.

"Iniesta's ability to create assists is one of the best in the world. You have to be very good at marking them both and limit their threat."

Milan have won their last seven games in Serie A.
