Full-time: Manchester United 0-0 Southampton
United are loading at the box at every opportunity here but Southampton are holding tight at the back. Time is almost up...
Stephens defends brilliantly, hooking the ball away just as Lingard had gambled on a loose ball inside the six yard area.
Three minutes of time added on here.
Pogba just launched a ball forward for Martial to race onto and there were seven United players still in their own half.
Boufal now heads off for Southampton with Nathan Redmond onto replace him for the final five minutes.
United have the ball in the back of the net! But it won't count. Young pings a low free kick in from the left that falls to Pogba who prods home at the near post, but the Frenchman was stood offside as he did so.
Martial slips a ball down the inside left for Shaw who wins a corner, but again it comes to nothing with the last touch coming off Rashford. Southampton are making another change now, with Long off to be replaced by Gabbiadini
Southampton work another opening with Long and Ward-Prowse exchanging passes before finding Tadic on the edge of the box. He has a moment to take aim, but prods his effort wide.
United have become slower and slower as this half has wore on; they haven't got close to getting in behind the Southampton backline.
Matic tries his luck from range again; this one is probably the worst of the bench. United are looking as clueless as ever with 20 minutes remaining here. They are lucky Southampton are having their own issues in the final third.
Young takes it and whips a cracking effort over the wall which veers just wide.
Instantly, Martial drives at the Southampton back line and wins a free kick. A bit of a generous decision, that one, there didn't look to be much contact.
Here's that change, Martial on for Mkhitaryan, who's had a truly dreadful day at the office.
Anthony Martial is preparing to come on. As he does that, Ward-Prowse pings in another peach of a free kick that De Gea just about manages to punch clear. His reward is being taken out mid-air by Jones. Thankfully for United, the Spaniard is back up on his feet,
Oh dear. Another left-footed cross from Mkhitaryan sails straight out of play. He was under no pressure there.
Boufal and Lingard both pick up bookings in the space of a couple of minutes.
Ashley Young might be in a bit of trouble later this week; the referee missed what looked to be a clear elbow on Tadic, landing one in the stomach.
Henrikh Mkhiatyran cuts in from the left, working the ball onto his right looking to shoot but his low effort is straight at McCarthy - who still hasn't been really troubled this evening.
United's front four at the moment is Mata, Lingard, Mkhitaryan and Rashford. It's looking pretty clueless out there at the moment, you wonder how long it is before Anthony Martial is introduced.
Southampton has started this half well. United; wretched.
De Gea denies Long! Southampton saunter through the middle of United again with Ward-Prowse stretching out to the right to receive the ball. He cuts a low ball back in to find Long's excellent run but the United goalkeeper somehow gets the ball over the bar.
Lingard pings an inviting ball across goal after being slipped through by Lindelof but Rashford can't stretch far enough to get on the end of it.
