Temi: Smalling's inability to use his left foot led to the goal. Even at the professional level you see things

AADZ: Nice 1 Mourinho, well done. Invite pressure with joke defenders. Self inflicted. Controlling the game and do that...

Mister Kai: Utd let one of the bottom teams dominate them. Pathetic...... Nothing else than pathetic.

Manchester United have brought Rojo on for Mata and have gone ultra defensive and tried to lock the door.

Middlesbrough have continued to put good quality balls into the penalty area.

Jesse Lingard's afternoon is over. His goal is the difference but an injury means he limps off to be replaced by Anthony Martial. He joins a game in which Boro have wind beneath their wings.

If United's players are indeed tired, this is when it will tell.

Paul Mitchell: Would have lost this under Van Gaal. Jose is clearly the right man to take United forward

DeathApeDisco: And so United begin to perform this strange, defensive style which invites pressure, when they should look for a third.

Seth Gogo Egoeh: Mourinho is too defensive. Bringing on a defender for an attacker. Doesn't he know that goal difference could be crucial?

Alvaro Negredo... so near yet so far. Another cross is designed for the Spaniard to finish but it skips a yard in front of him and goes out for a goal-kick.

The home side are throwing everything they have at United, but it is coming to nothing.

Son Heung-min is the man to lead the line for Tottenham in Harry Kane's absence, while Christian Eriksen starts after coming off the bench against Millwall last weekend.

Mauricio Pochettino brings Mousa Dembele and Kyle Walker back into his starting XI, for Harry Winks and Kieran Trippier.

Spurs: Lloris, Walker, Dier, Alderweireld, Vertonghen, Davies, Wanyama, Dembele, Alli, Eriksen, Son.

Southampton stick with the same side that beat Watford 4-3 last time out, with Claude Puel's side in goalscoring form having netted four on their past two outings.

Southampton: Forster, Soares, Stephens, Yoshida, Bertrand, Romeu, Davis, Ward-Prowse, Tadic, Redmond, Gabbiadini.  

Traore is quickly into the action. His deep cross finds Negredo but he can't generate enough power on his header to get the ball back into the danger zone. 

Poor Tom. Still, not every day you get tweeted about by an Olympic gold medallist.

United also make a change. A defensive one. Juan Mata is replaced by Marcos Rojo.

Boro go for broke. Gaston Ramirez and Grant Leadbitter are replaced by Rudy Gestede and Adama Traore. Pace and size. Can they use it?

Chance! Alvaro Negredo hasn't had the best of service so far but he gets a decent cross here. Unfortunately, after diving in ahead of his marker in the box he can only steer the ball wide.

United could end winning this by plenty. Boro have to come out now and the visitors have pace and skill on the break. 

Tom: Still can't see the point of Lingard 

El Sizzy: Seriously don't understand what Rashford is playing at today. He's been really poor in finishing touches and passes.

Marcus Rashford is having a 'mare with his final ball. He collects on the right but fires a terrible cross (shot?) high and wide.

With Rashford and Lingard, United can turn defence to meaningful attack in a flash. After the corner, they launch the ball forward but after breaking clear, Rashford has to check and the chance evaporates.
