Lazio moved up to third in Serie A as a second-half penalty by Ciro Immobile secured a 1-0 victory at mid-table Udinese on Sunday and boosted their Champions League qualifying hopes.

Lazio have 68 points and lead fourth-placed Inter Milan by two points and AC Milan in fifth by four with two games left. Juventus are second on 69 before they visit Empoli on Monday.

Immobile and Luis Alberto had the best chances to break the deadlock for Lazio in the first 45 minutes. Immobile came close with a header, while Alberto's strike brushed the woodwork.

Immobile had another chance to put Lazio ahead just after the break in a one-on-one with Marco Silvestri but the keeper produced a remarkable one-handed save to keep him at bay.

Lazio got a break in the 61st minute when Immobile was fouled by Adam Masina in the box and he converted the penalty.

Udinese, who are 12th with 46 points, thought they had equalised late on through Ilija Nestorovski's header but it was ruled out for offside.

Lazio host relegated Cremonese next Sunday before finishing the season at Empoli on June 4.
