Huge chance and Norwich will be wondering how they are not 1-0 up.

They are so quick on the counter and play out right from the back with Anis Ben Slimane playing Jack Stacey into acres of space down the right.

He runs into the box in a one-on-one but takes probably one too many touches and manages to drag his shot across the empty goal and wide.

Can Pompey hold on for a first win in eight league games with 10 men?

A massive 45 minutes or so to come in the context of the relegation battle.

We are back underway at Fratton Park.

We need to move them about, Cameron Brannagan and Yunus Konak, you don't need both of them there, push one of them higher up so there's options in front of the ball.

It's about tactical tweaks now.

Femi Azeez has a shot for Millwall but it sort of sums up the game for them so far, as he drags it miles wide of the post.

That was the best chance of the game so far and those types of chances are the difference between winning, losing or drawing this game.

Is Mathias Kvistgaarden your out-and-out centre-forward?

If he is the centre-forward he has to be taking those chances.

Another excellent chance goes begging for Norwich as Anis Ben Slimane threads the ball through to Mathias Kvistgaarden in the box but he loses his footing and his shot is tame and easily saved by Anthony Patterson.

Millwall on the edge but can Norwich capitalise on this dominance?

Kenny McLean quickly loops the ball forward on the counter for Norwich and he almost releases Mathias Kvistgaarden but he's hauled back by the offside flag, by the narrowest of margins.

Good opportunity for Norwich, almost.

This is all Norwich at the moment, if they take a little bit more care.

The move with Ali Ahmed a few minutes ago is a great example, it takes just that little bit more care.

There's been no real chances at this moment, pick the right pass out and take that care.

Millwall were starting to string a few passes together of their own but it doesn't quite seem to be clicking for them as Jake Cooper mistimes his pass and it goes out for a throw-in to Norwich.

The Canaries immediately pounce and get the ball straight into the Lions' box - the visitors definitely look the more confident of the two sides at the moment.

No real chances at either end yet at The Den as we approach the 20-minute mark.

Camiel Neghli tries to create something for Millwall, but his little pass through into the box is too heavy for Barry Bannan and runs behind for a goal kick.

An electric first half ends with Pompey ahead but down to 10 men.

Keshi Anderson marked his 31st birthday with a first Pompey goal on his first start for the club but Portsmouth's joy only lasted eight minutes before it was thwarted by a red card.

Connor Ogilvie was sent off after a hefty challenge on Stanley Mills and while Portsmouth haven't been made to suffer yet, there's still another 45 minutes to come.

Another absorbing 45 minutes, no doubt.

It's all Norwich at the moment, as they pass the ball around with ease making Millwall work across the pitch.

Lots of patient build-up play from the visitors.

Keshi Anderson plays in Jordan Williams on the left flank and there appears to be a moment of hesitation from U's stopper Jamie Cumming.

It's only brief though and the keeper decides to be bold, running off his line to smother the ball before Williams can get a touch.

A second Norwich corner comes flying in from the other side towards the back post and it bounces around for a while, with Millwall unable to clear.

Pelle Mattsson's looping kick sends it back into the danger area before Anthony Patterson manages to get his hands on it.

The job to do is easier for Portsmouth, to be destructive and to sit in, but they have to do it right every time.

Oxford just have to do it right once.

You would expect Oxford to have the ball higher up the pitch in the second half and put Pompey on the back foot.

Oxford are turning the speed up a notch to try and increase the pressure on 10-man Portsmouth but the visitors can't break the Pompey line yet.

Yunus Konak works his way into position on the edge of the box but might have taken a little too much time on the ball to see his effort blocked.

Norwich are here for a game and they're getting the tempo going.

They're trying to play the ball in behind Jake Cooper and that's where they've got the best chance at making something.

Millwall's Josh Coburn goes down in the box as he tries to get on the end of a threaded ball, and jumps up with his arms in the air claiming a penalty.

But the referee is having none of it and the linesman also has his flag raised for offside anyway.
