Manchester United slipped to third in the Premier League as they were held to a frustrating goalless draw by Southampton at Old Trafford.
Jose Mourinho's side also lost striker Romelu Lukaku to a serious-looking head injury as they were forced to settle for a point for a third game in succession.
The hosts had a strong penalty appeal turned down and had a late Paul Pogba goal disallowed for offside, but Saints arguably deserved a point for their resilience.
Before he went off after a nasty clash of heads with Wesley Hoedt, Lukaku headed over a glorious early chance for United, while Jesse Lingard also put a header narrowly wide.
Lingard also appeared to be frustrated by the hand of Maya Yoshida in the box, but nothing was given by referee Craig Pawson.
