Romelu Lukaku’s strike earns another three points for Manchester United

Seven months on from edging an entertaining EFL Cup final against Saints, United arrived at St Mary's looking to maintain their fine start to the campaign against a team struggling for coherence and goals on home turf.

United were made to sweat as Mauricio Pellegrino's men launched wave after wave of attacks in the second period, but Lukaku's first-half goal was enough to secure a 1-0 win, taking his side to a club record-equalling 16 points at this stage of a Premier League season.

However, while it may have been a successful trip on the field, things did not go so well off it. Mourinho was sent off in stoppage time by referee Craig Pawson for his antics on the touchline, while in the first half some supporters went against United and Lukaku's plea to stop chanting a song about the striker that Kick It Out have called "offensive and discriminatory".

United are understood to be preparing a strong response after the song echoed around the ground following the Belgian striker's eighth goal in as many games for his club, having tucked home after his initial header was denied by Fraser Forster.
