Liverpool are looking more of an attacking force already this half.

Luis Diaz is proving a real handful.

An attempt by Joe Gomez. Not bad but it's off target. He will score one day.

There's no doubt Jurgen Klopp will demand his players to be braver on the ball than they were in the first half.

Wonderful run by Bukayo Saka who looks like he is about to get away from Joe Gomez inside the Liverpool box but the defender does well to frustrate his opponent in the end.

No changes by either side at the start of the second half.

Kai Havertz goes down near the halfway line and Arsenal's fans are screaming for a free-kick.

John Brooks waves play on.

The good news for Liverpool is that it is still 0-0 and they're still in it.

I think Jurgen Klopp will be delighted with the score but not the performance.

Will Arsenal ever score again? Will Liverpool get better? Will this go to a replay neither team really wants?

Back under way.

Liverpool need more intensity and energy and more care on the ball. That's the key.

Nottingham Forest

Nottingham Forest boss Nuno Espirito Santo, speaking to BBC Sport: "We are disappointed with the way we started the game and conceded. It's not the way we want to do things. We were too slow. We conceded very easily.

"It makes our task much harder. Credit to the boys for the way we reacted. We had chances to finish the game. We have to solve it there. It will be hard, but we are ready for it."

On whether fatigue was an issue: "No I don't think that. There were not too many spaces. We didn't have the speed of the ball to create that. I would not say it was fatigue. We couldn't find the right passing lines to break through Blackpool. The issue was not what we couldn't do, but what we conceded.

"We had good chances, and there were good saves from their goalkeeper. This is positive and how we want to do things, we just need to be more clinical."

On changing winter break plans: "Yeah definitely. We had a plan but now we have to change it. That's part of the job."

On scrapping replays: "It's something that everybody is considering because of the amount of games for everyone involved. It could be a solution."

Happy to still be in the FA Cup though? "Of course, it's a competition we love very much. Our fans were amazing again so we have to go to Blackpool to do it."

Luton Town

Luton manager Rob Edwards: "Disappointed not to win the game. It was pretty much one-way traffic in that second half but we’ve hit the woodwork, we’ve huffed and puffed and had a nailed on penalty - and I don't see the point of VAR if it's not going to overturn that decision.

"That's really frustrating. I never blame that but that was a mistake.

"The players performed well, we just couldn’t find that goal to get us over the line. Credit to Bolton, they've done well but we should have won the game."

On penalty not given:"I will go and have a word to ask the question. I am [disappointed the referee didn't get to have a second look], I think he should have."

On missed chances:"I still believed that we could do it. The next action [after Alfie Doughty hitting the inside of the post] was the penalty, the non-penalty.

"We believed right to the very end that we could find a way to win but today it wasn't to be, our schedule changes a little bit and we have to go and do it in the replay."

On schedule changes:"We play Burnley now on Friday rather than Monday so our week looks different. We were prepared for it, we were ready, we hoped it wouldn't be the case but we haven't got through today so we've got to do it another way."

On importance of FA Cup:"We completely valued this game today, it was important to try and get through, respect Bolton because they're a very good team, they're riding high and confident.

"I love this competition and I want to do well in it as well. So we went for it, we wanted to win the game. No doubt about it."

Bolton manager Ian Evatt: "At the start of the second half, we didn't manage that spell well enough.

"First half I thought we edged it, actually. I thought we were the better team, we had some moments, some good patterns of play where we just didn't make that final pass or make the right decision.

"Second half we went a bit safe, they put the pressure on but we defended our box really well which was great.

"Then the last 10 minutes, we got in the ascendancy and were waiting for a drop of the ball or something we could finish but it didn't quite happen."

On team dropping deeper second half: "That's not the way we do things really. When you see cup shocks really, you see the lower league teams hanging on for dear life but we didn't want to do that. We wanted to win on merit and take the game to them.

"I think we did that. Yes, we rode our luck at the start of the second half and that end was almost sucking the ball into the goal at times but we defended the box great.

"Then we perhaps could have nicked it at the end."

On penalty incident: "I haven't seen it. I don't know and I didn't really know what was happening because we're not used to VAR in League One!

"What I will say is that the referee has made a decision and there are two experienced referees in the VAR hub as well so if they have made a decision that it's not a penalty then it's not a penalty."

On confidence from the result: "It's no good coming here today and it being a one-off, we need to sustain these performances, be consistent with what we're doing and hopefully we'll have a chance of getting back to the Championship. And also causing an upset in the replay.

"We have to keep going, consistency is the key for us. We're know what we're capable of, it's just doing it on a more regular basis.

"This club has been through the mill as everybody knows, the fans have suffered, and we're trying very hard to build it up to what it once was.

"Extra revenue from the replay, hopefully getting a full house at our stadium, will go a long way to getting us back to where we want to be."

Huddersfield Town

Huddersfield boss Darren Moore, speaking to BBC Sport: "I’ve got no fault with the players. We set our stall out and disrupted everything. Once the goal goes in we lost a bit of concentration for 10 minutes and then regained it. I take nothing away from them, we know what a good and a fluid team they are. Credit to the boys in terms of how they went about the game today.

"What they do is, the ball sped is fantastic, they test you in wide areas but they’ve got inverted runners so there’s so many aspects of the game you have to stay concentrating on. It was a wonderful learning experience."

On new signings: "I'm really pleased with Bojan Radulovic and Alex Matos, what they gave us in midfield and up front. The supporters must have saw what they're going to give us for the second half of the season. Those two alone will improve the team."

Blackpool boss Neil Critchley speaking to BBC Sport: "We would have liked it to be 2-0 before half-time obviously but that goal just before brought them back into the game.

"I thought our players were excellent. They caused so many problems but I thought we defended well and carried a threat. To come away from home and get a draw sets us up nicely for a replay at Bloomfield Road.

"That was the plan. We knew coming away from home and the quality the Premier League players have now, we would have to suffer at times. I thought we suffered well and could hurt them with pace on the counter-attack. The two goals were really good goals. CJ Hamilton has done that countless times this season, getting forward.

"We had to withstand pressure in the second half but it took a fantastic strike from a fantastic player to get them a draw.

"They hit one past the post and one over [the bar] but you need your goalkeeper to pull out those saves. You will need luck, moments to go for you and for your goalkeeper to pull off moments like that.

"We're delighted. 2-2 in the FA Cup and now a chance for an upset. We might be on the TV, who knows? Let's get back to Bloomfield Road and have a right go. The supporters came today and appreciated the way we played. It was a full house here and it was brilliant."

West Ham United

West Ham boss David Moyes: "I'm really looking forward to it [going back to his former club for a replay]. I've not been back that often.

"I thought we started very well. We should have been 2-0 up. Pablo Fornals had a great chance. We got a bit slack after that.

"To be fair to Bristol City they came into the game and thought they had a part to play in it.

"We were the better team in the first half but didn't finish it off.

"We missed a couple of chances. Bristol City played well. We didn't play well in the opening 30 mins of second half.

"We've played a lot of games this year. Another one added to it will be fine."

Patrick Bamford speaking to BBC Radio 5 Live about his wonder goal: "It was hard today there was a few chances leading up in the build-up you had to concentrate on your touch.

"It was a hard pitch it brought back memories being on loan at MK Dons I have played here before and that is the beauty of the FA Cup.

"With a volley you don't have to worry about the pitch!

"I knew the connection was good and it was nice to see."
