A glimpse of goal for Patson Daka as he latches onto a pass from Ricardo Pereira (in a very advanced position for him) but fires a rising 20-yard shot over Vlad Kovacevic's crossbar.

Pompey left-back Zak Swanson is getting forward a lot so far today.

He drew a save from range from Ivor Pandur early on with a decent low effort but this one is more routine as his right-footed effort drifts harmlessly at the Croatian.

Leicester are just sitting further back at the moment, and Norwich are playing some good football around the Foxes' net.

It feels as if it might be a matter of time before the deadlock is broken - Leicester are really going to need to dig in to get out their own half.

Worst feeling in the world.

Mathias Kvistgaarden gets his head on a near post corner and sends it into the side-netting.

The away fans go wild as the net ripples but a couple of seconds later reality strikes and the home fans have some fun.

Very poor marking from the Foxes defence, however. A let-off.

The good and bad of Rovers forward Yuki Ohashi in one move.

He produces a superb turn in the area in taking Moussa Baradji's pass beyond Matt Clarke.

But rather than find the net, Ohashi drives his effort across the face of goal.

The Japan forward does so much good work, but the goal tally does not match it.

We are now less than a month away from Northern Ireland's World Cup qualifier with Italy in Bergamo.

Before then, Blackburn have four more games in the league, so Michael O'Neill has a lot on his plate.

March is going to be very busy for the man with two hats.

The pressure is intensifying with Paris Maghoma and Ali Ahmed cutting through the Foxes defenders in the box.

A clash of heads in the box will lead to a break in play and the chance for Gary Rowett to reorganise his troops.

Good spell from Norwich but Ben Chrisene's final ball from the left of the box is nodded behind by Caleb Okoli and the Foxes are able to deal with the follow-up from the corner.

Most of Norwich's best stuff is coming down the left through Chrisene and Ali Ahmed.

If we had VAR in the Championship they would have taken a long time to look at the disallowed goal earlier on in the match, and now the penalty appeal.

Ivor Pandur has had to make some great saves though.

Regan Poole forces a decent save from Ivor Pandur as the visitors fail to clear from a corner.

Pompey pushing.

After Abdul Fatawu's shot is charged down on the edge of the box, the ball breaks to Harry Winks to unleash a 25-yard fizzer which is uncomfortable for Vlad Kovacevic, moving in the air and just to his right but he gets down well to parry away in slightly unorthodox fashion and his defence are able to complete the clearance.

Terry Devlin, who got a couple at Charlton the other week, has a pop from range that Hull keeper Ivor Pandur spills out.

Colby Bishop thinks he should have a penalty for a pull by Charlie Hughes as he looks to get on to the loose ball but nothing doing.

An early corner from Blackburn, showing positive intent, which Derby goalkeeper Josh Vickers gathers at the second attempt.

It's worth noting that Derby have taken as many points at home as Rovers have on the road. It feels like a lot of Blackburn's bother this season has come from poor results at Ewood Park.

A couple of clever early passes from Paris Maghoma, dropping deep into space between the lines, has given Norwich some attacking intent but, for now, Mathias Kvistgaarden has not managed to capitalise on them.

Norwich popping it around with all the confidence you'd expect of a team who have won four of their past five away games.

There has been a good press from Leicester so far, and you can see that since Gary Rowett has come in.

The whole team are working harder off the ball.

Portsmouth having the better of these first few minutes.

Moving the ball around with some purpose.

That early Zak Swanson sighter from range is their only effort on goal so far though.

Bobby De Cordova-Reid gets a touch unfortunate as Ricardo Pereira's ball to send him clear down the right channel bounces off his heel, denying him a run into the box.

Norwich spring forward immediately but Mathias Kvistgaarden has to settle for a corner off Caleb Okoli, which is hacked away from the near post by the first man.

It's one of those Blackburn old boys who almost brings us the first goal.

Ben Brereton Diaz gets on to a long ball over the top, away from ex-Derby defender Eiran Cashin and he brings a good save from a tight angle from Balazs Toth.
