Pompey's three-match winning streak is coming to an end as it stands. John Mousinho is doing all he can to prevent that from happening.

The Portsmouth boss sends on Christian Saydee and Cohen Bramall, having already added Kaide Gordon and Kusini Yengi to the pitch.

Derby have been so organised, they've made it so difficult for us.

In terms of work-rate, organisation skills, they've done really well.

No doubt that has come from the effect of John Eustace.

More Stoke boos for a sub, this time it's as former Potter Tom Ince is withdrawn by Watford, with Moussa Sissoko and Vakoun Bayo sent on to try to win it, and Mamadou Doumbia also heading off.

Giorgi Chakvetadze has been booked for tugging back Junior Tchamadeu too.

Morgan Whittaker is learning the definition of insanity.

Shot No.6 of the afternoon - all of them from long-range - and for the third time Jacob Widell Zetterstrom is forced into a smart save.

A lifeline?

Harrison Burrows is, harshly if you ask me, adjudged to have handled a cross from Paul Smyth in the box after turning his back on the ball.

Michael Frey steps up to take the spot-kick...

Cor, huge boooos ring around the Bet365 as birthday boy Ali Al-Hamadi is subbed off by Mark Robins, with Sam Gallagher coming on.

He's been a bright spark for the Potters today, but Watford have taken hold of the game since the interval.

If Boro are going to score today, you'd have to favour Morgan Whittaker to be the match-winner.

The former Plymouth man forces Jacob Widell Zetterstrom into a falling save to push away the powerful low strike.

After returning to the Blades XI this afternoon, Gus Hamer has been taken off on the hour, to be wrapped in cotton wool, no doubt.

Hamza Choudhury is also withdrawn, with Rhian Brewster and Femi Seriki sent on by Chris Wilder.

If Watford can't score, maybe Stoke will do it for them?

Ben Wilmot gets his head on Imran Louza's deflected inswinging cross from the right but it loops past Viktor Johansson and comes back off the upright.

Pompey have been more of a threat in the second half, but the Hatters are still looking dangerous.

However, this won't live long in the memory as Isaiah Jones almost picks out the back row of the stand after a game of ping-pong in the Portsmouth box.

A shot on target!

Glovework!

It's Giorgi Chakvetadze again for the visitors, making a bit of space and firing in a shot from outside the box which Viktor Johansson holds.

Moments later and the Hornets fans think they have the lead, but it's not long before the agony of realising that Yasser Larouci's deflected effort hit the side-netting sets in for them...

Luke Ayling has been struggling after Jerry Yates fell on his ankle a few minutes ago. And he's going to have to go off.

Ryan Giles goes on which means a re-jig, with Neto Borges moving across to centre back.

Leeds' draw against West Brom earlier means Sheffield United are on course to close the gap to three points.

Technically the Blades will need four points to overhaul Leeds as their goal difference is far inferior.

Andre Dozzell's long-range effort is blocked by Liam Walsh, before Adil Aouchiche has his free-kick stopped by the wall before it gets close to Thomas Kaminski.

Pompey have come out much better in the second half, but are yet to register a shot on target.

Some action... but still not a shot on target.

Giorgi Chakvetadze glides down the left for the visitors, drifts inside and sends a curling effort from just outside the box not far past Viktor Johansson's far post.

We're still in control.

When we go forward we're picking up the loose ball.

It's been aggressive in the final third.

Normal service has resumed. Boro have the ball, but Derby are keeping them away from their goal.

On this occasion, Morgan Whittaker gets the ball to sit up after his first touch, but the shot is comfortable enough for Jacob Widell Zetterstrom.

Stoke stopper Viktor Johansson and his opposite number Egil Selvik didn't need their gloves in the first half... Mark Robins and Tom Cleverley will be hoping for far better in the final third in this second period.
