Former Liverpool manager Benitez took charge of the European champions in the summer after the departure of Jose Mourinho.

The visitors took the lead when John Arne Riise beat his marker to slide past the keeper on 21 minutes.

Goran Pandev brought the score level three minutes from the break after capitalizing on a defensive lapse.

Samuel Eto'o hit a brace on 70 and 80 minutes to complete the rout which gave Inter their fourth consecutive title.

The Nerazzurri had previously won the Serie A, and Italian Cup and the UEFA Champions League.
