Southampton twice thought they had scored second-half goals only to be denied each time for offside in a 0-0 draw at Fulham.
In a first half of few chances, James Ward-Prowse came closest to a goal but his free-kick hit the crossbar before Che Adams was unable to convert on the rebound.
After the break, Ivan Cavaleiro headed over a fine cross from Antonee Robinson following a swift counter-attack by Fulham.
Shane Long thought he had put Southampton ahead on 76 minutes but the striker was offside when Ryan Bertrand had passed to him.
Theo Walcott then suffered a similar fate with five minutes remaining, as his effort was ruled out following a VAR review after Adams was offside in the build-up.
Fulham remain 18th, on 11 points, while Southampton drop to ninth with 25 points.
