Romelu Lukaku secured Manchester United a hard-fought victory at Southampton as Jose Mourinho's men managed to batten down the hatches after half-time.
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 that takes them to a club record-equalling 16 points at this stage of a Premier League season.

Star man: Romelu Lukaku. The striker secured all three points by scoring the game's only goal and, on an afternoon when United struggled to convince, was a consistent and effective focal point in the final third. In the same way he contributed so much on the rare occasions his team threatened, he occupied Southampton's defence as they grew in confidence in pursuit of an equalising goal.
In with the crowd: Lukaku may have become the latest to discourage United's supporters from using the controversial chant anti-discrimination group Kick It Out have described as "offensive and discriminatory" but it has not stopped them doing so. The lyrics used reference the size of the 24-year-old's penis, and were sung again after his first-half finish gave United the lead.
Data point: This was Southampton's 11th league defeat of 2017, which equals their total throughout 2016 at a time when they are scheduled to play a further 15 fixtures. There is perhaps no finer demonstration of their decline under previous manager Claude Puel, which his successor Pellegrino is yet to arrest.
