Macedonian striker Goran Pandev slotted in a scuffed shot from Samuel Eto'o after six minutes to grab his third goal since rejoining Inter last month.

Defender Walter Samuel then powered in a header from a corner and Argentina's Diego Milito netted his 14th goal of the league campaign after a fine move just after the break for a final score 3-0.

Cagliari felt hard done by when Alessandro Matri's goal was ruled out for offside despite replays suggesting otherwise.

"We can definitely improve a lot more but I'm happy for the three points. We are only thinking about ourselves, other results don't bother us," Pandev, whose relentless side are coasting to a fifth straight scudetto, said.
