Inter Milan took a stranglehold on the Serie A title with a 3-0 win over Cagliari on Sunday which saw them open a 10-point lead over city rivals AC Mlan, who could only manage a goal-less draw at Bologna.

Milan's draw continue their disappointing form which began with a defeat in the derby match against reigning champions Inter two weeks ago.

Since then they have drawn their next two matches, with Inter taking full advantage, although they are facing a renewed challenge from Roma, who have gone 12 games without defeat. Goals from Goran Pandev, Walter Samuel and Diego Milito earned Jose Mourinho's Inter side a comfortable victory in the San Siro, taking the lead after just six minutes.

Samuel Eto'o, playing his first game since returning from Africa Cup of Nations with Cameroon, set up Pandev to score at the near post.

The second came after 20 minutes as central defender Samuel headed home a Maicon corner. Cagliari had a goal chalked off for offside which TV replays showed should have stood and Julio Cesar pulled off a brilliant save to deny fellow Brazilian Nene.

There hopes of a revival were ended in the early stages of the second half as a neat move involving Eto'o and the excellent Pandev saw Milito score the third.

Milan had the better chances at Bologna and Ronaldinho hit the crossbar with a spectacular effort in the second half. Late on, captain Mansion Ambrosia also saw an effort rebound off the woodwork.
