Marcel Sabitzer knocks it back to Antony but his strike lacks power and rolls into the keeper's arms.

Wout Weghorst is not a small man playing up front, he is huge so go and give him something attack. It is simplistic football a little bit but if you aren't putting balls into the box why are you playing Weghorst?

Southampton are throwing bodies forward. Kyle Walker-Peters sends it into the mix but it's scrambled away before a header by Lyanco drops just wide. James Ward-Prowse has made a big difference since coming off the bench.

The final ball from Manchester United hasn't been good tonight. Perhaps there is a bit of a hangover from the cup final and you could probably accept that.

Another big chance for Anass Zaroury as he finds himself in space in the box. The angle is tight and he hooks it into the side-netting.

Back under way at Old Trafford.

A huge final 20 minutes of normal time coming up. Will Grimsby hold on? They've given this everything but they're starting to creak at the back.

This will surely have an impact. Casemiro is on for the second half, replacing Scott McTominay.

Shaun Rooney is frustrated as the offside flag goes up when he's trying to run in behind.

Fleetwood are doing a good job this half.

Spurs have not had enough runners to take Sheffield United on, if they play quick like they have at the back end of the first-half they will cause issues for Sheffield United.

Josh Vela thinks he has escaped into the box but he's penalised for an earlier foul on Charlie Taylor.

JUNAID: Antony on the right constantly going down the line and turning back on to his left food is soo frustrating.

shaun holroyd: As a Grimsby fan, any premier team would have been a good draw for this round, no matter the score, but Southampton felt doable. It seems the players feel the same way! Come on you mariners!

A tough night for Fleetwood now.

Anyone still awake?

As expected, it's all Burnley at the start of the second half and Vitinho has carried on where he left off. He'll fizz in crosses all night.

Grimsby v Manchester City in the quarter-finals anyone?

The League Two club are 30 minutes away from delivering a HUGE shock.

He has to do better! That is a big mistake from Hojberg, but that is a terrible finish!

What a miss!

Tottenham gets themselves into a right mess at the back and Ismaila Coulibaly is through on goal but slices it horribly wide.

Big chance for the Blades. Not taken.

Off we go again at Turf Moor where Fleetwood have a big second half coming up, down to 10 men.
