Luton have the momentum behind them now. Alfie Doughty angles a shot towards the bottom corner but Regan Poole gets himself in the way to deny the Hatters a second goal.

A comical moment follows as the ball gets stuck on the roof of the stand.

A sight of goal for the home side as Lewis Koumas collects a pass from Ali Al-Hamadi and drags wide of the Hornets goal from just inside the area.

Al-Hamadi is causing the Watford defence problems with some pacy and powerful running.

It is a familiar feeling for Portsmouth. They have have conceded 30 first-half goals in 35 games - only Plymouth Argyle (32) have conceded more in the Championship this season.

There's huge danger signs for the Rams.

The Boro attackers are getting acres of space.

It just feels as though it's only a matter of time before Middlesbrough make a breakthrough.

Good spell from the Hoops and it's Yang Min-Hyeok again who fires an angled shot wide of Michael Cooper's goal after Hamza Choudhury's tame clearance header.

And there's the confirmation in the live Championship table that Luton are off the bottom.

Still a long way to go at Kenilworth Road though... and the Hatters aren't used to winning this season.

Michael Cooper produces a good save, getting down low to his left to save a powerful shot from Rangers' Tottenham loanee Yang Min-Hyeok, who gave away the ball for the Blades goal and is clearly keen to make amends.

Regan Poole and Nicolas Schmid have a miscommunication at the back for Pompey. The centre back pokes the ball around his own goalkeeper before Schmid gets back in time to take the ball away from danger.

That's the sort of gift that Luton need at the bottom of the table.

We're just starting to pick up the tempo and put pressure on their defence.

So far what I like about the front players is they're all switching around. There's lots of movement which is causing a nuisance for Derby.

Stoke's Bae Junho is a very accomplished footballer, but you wouldn't know it from this woeful free-kick, from a dangerous position near the left edge of the Watford penalty area, with his attempted cross sailing clean into the stands.

Boro are piling on the pressure. Marcus Forss has one shot from inside the box saved by Jacob Widell Zetterstrom before his rebound is blocked by Sondre Langas.

Then Morgan Whittaker strides forward on the right, but he flashes his effort across goal.

Tom Ince is copping some flak from the home fans this afternoon after an, er, underwhelming spell with the Potters.

He's in the right place at the back post to block an effort from Enda Stevens after Lewis Koumas' deep cross from the flank.

Luke Ayling sees the world open up for him from 30 yards out. He tries to curl one into the top corner but Jacob Widell Zetterstrom can drop a hat over the tame effort.

At the other end, Thelo Aasgaard slices an effort well wide.

Pompey get forward for the first time. Some good inter-play down the left sees Josh Murphy fire a cross in for Colby Bishop, but his header is deflected behind.

I think we've been as good as we can be, the midfield have looked fairly good so far.

The concentration levels is going to be one thing we'll have to be spot on with today.

First attempt on goal of the game but Watford's Edo Kayembe can only drag his effort from just outside the box wide of Viktor Johansson's goal.

Andre Dozzell has absolutely flown into a tackle on Liam Walsh. The Luton man flung up into the air. Dozzell goes into the book after the referee clears up some argy-bargy.

It's been a scrappy start so far.

Derby are pressing slightly but they're allowing us to have the ball.
