Chelsea hero Ruud Gullit is warning Arsenal going into their Europa League tie with AC Milan.

Under Rino Gattuso, Milan are unbeaten in 11 games in all competitions since the turn of the year and have conceded only four goals.

"Arsenal is going to face a good team," said Gullit, who won Serie A three times and the European Cup twice in six years at Milan.

"Not a team of stars, not one you identify with certain people, but they have become stronger as a team.

"Against Roma they played well, a different system, one striker up top on his own and one floating a bit."
