Bruno Fernandes broke the deadlock 10 minutes after the break with a precise side-footed volley to give United the three points they just about deserved.

The Saints, who will take heart from their performance, survived an almighty goalmouth scramble in the first half when keeper Gavin Bazunu saved from Anthony Elanga and Armel Bella-Kotchap blocked Christian Eriksen's follow-up.

United broke through when Fernandes met Diogo Dalot's cross and as they closed out their second successive win and first league triumph on the road since February, Ten Hag was able to introduce Casemiro, the new £60m acquisition from Real Madrid, as a late substitute.

United grind out victory

United could not afford to slip up at Southampton after the manner in which they overcame Liverpool or they would face charges that they had simply raised their game against their greatest rivals.

And while it was hardly a vintage performance, this was still a vital win - and Ten Hag will take great satisfaction from a clean sheet and three points.

Fernandes' moment of quality settled a tight and competitive game in which United had to survive late pressure from the hosts with new defender Lisandro Martinez prominent and keeper David de Gea making a fine save from Joe Aribo's header.

The visiting fans demonstrated their delight at the final whistle - while once more noisily chanting their desire for the removal of owners the Glazers - and were also able to get a glimpse of new marquee signing Casemiro when he appeared as a late substitute to shore things up.

Not a classic, but United and Ten Hag will happily take this as they embark on the slow rebuild from the crisis that threatened to envelop the club after defeat at home to Brighton and that 4-0 debacle at Brentford.
