Eddie Howe said:

"It's a massive win for us. Away from home we have questions to answer and that is a big step forward for us.

"I wasn't totally satisfied (at half-time) and the lads know they have to perform. We have the ability to make those changes. I have to credit the players who came on. Everyone played their part and it is a massive win.

"I got the sense (of urgency) at the start of the half and then there was bit of a lull and Fabian's goal injected confidence. 

"It took a moment of real class from Harvey (Barnes) and then we had cramp and all of those battling qualities at the end to get over the line.

"I think we are stepping forward in terms of our performances. I think it was a step in the right direction. 

"We can improve in lots of different aspects and that is what we are going to be working on this week. We are a really tight-knit group and we have to remain that way.

"I think it’s a great platform for us. Confidence is always the key ingredient in any sporting team, and hopefully by winning in the manner we are, that confidence level will continue to grow.

"There’s no doubting the quality of players we have, albeit that we’re small in numbers so we can’t afford to lose anybody. Winning is everything. I’ve never shied away from that as manager of Newcastle United.

"Winning is everything. The best way to do that is to be unified – that means the players, the supporters and the coaching staff and I’ll do everything to keep that unity.”

"It fell in line with other games this season. We’ve played really well in passages but not all the way through. What shines through is the ability to find a way through. We can get better but on the whole it was an improvement.”

On the half time changes:

"I’m sure there were a number of players who were disappointed not to start. We made changes to the team that played against Tottenham. They were tactical because every game is very different and I have to find what I believe is the best way to win the next game.

"It’s no reflection on the players that came out, but the most important thing is that the players respond in the right way because their best chance of playing in the next game is determined by how they perform on the pitch.

"I thought all three half-time substitutes did really, really well. I was really pleased with Sandro and Joe, and of course really pleased with Harvey, whose finish was incredible.

"I just felt we needed a different energy in the team, and I also think it’s reflective of the quality of players that we have waiting to play.

"I wanted to give them long enough to influence the game. I didn’t want to cut their time too short where they couldn’t grab the game as we needed them to.

"I was really pleased with the attitude when they came onto the pitch. The ability of the players is not in question – I thought they all made a positive difference for us.”

On Alexander Isak:

"It was his eye, but I’m not 100% sure what the issue was. I just knew he had to come off. We’ll find out more afterwards. 

"I don’t know whether it’s serious or not, but we absolutely hope not. He’s such an important player for us.

On the equaliser:

"It was what we needed. We’d had a few moments, but we hadn’t had the clear sight of goal we would have wanted.

"It was maybe going to take something like that, a long-range effort, speculative to a degree, but Fabby has the quality to score those type of unbelievable goals for a centre-half. 

"It’s another one to add to his collection, and that gave us a lift and changed the dynamic and the mood in the stadium. It was an absolutely pivotal moment in the game.”

On the winner:

“He (Harvey Barnes) had a difficult season last year, going to a new club with a big transfer fee, he picked up an innocuous injury against Sheffield United and it hurt him and us. 

"He is one of the best finishing wingers I have ever seen - quality goalscoring wingers are few and far between.”

On Nick Pope:

"I’m really pleased for Nick. Whenever a player goes away on international duty, it’s always a different dynamic.

"With the players that we keen here, we can really focus on what they’re doing and we’re in tune with their performances.

"When players go away, they miss our contact time and there’s always that trust about how they’re going to come back, but you can see how Nick has come back, and the effect he has on the team. 

"He made two or three great saves that ultimately end up helping us win the game. He’s a top-class goalkeeper and I’m delighted for him.”

Gary O'Neil said:

"I think frustration is the right word. It is easy to feel down after results but the group gave everything. They showed loads of quality and I thought we probably edged it. 

"I felt really comfortable and really dangerous. We know we are in a tough run of fixtures and playing teams that have real quality and we are being punished for every error.

"The first goal we concede is desperately unlucky and summed up where the game was heading. Schar ended up taking shots from there, it flicks off Daws and goes in. Second goal I’m really disappointed with because we speak to the full-backs about showing wingers outside all the time, literally every day since I’ve been here.

"Harvey Barnes is allowed to come inside and it's a fantastic finish, but it should never happen against us, so I’m disappointed with that. Nels (Semedo) having to come off was a big blow because he’s really important to us. We need to make sure that he can get through more of the game than he did today.

“But all that group could do is give everything, and show what they are, and you can see big moments of quality. I have no doubts that we’re going to pick up some big results if we continue to put in performances like we did today.

"The first one’s a deflection, but it can happen. We're not feeling sorry for ourselves or saying, ‘Oh, it's just one of those things’. It's not that, we had enough opportunities in the game, we hit the post at 1-0, Jorgen has a really good chance for header at 1-0.

"At one-nil I thought we looked the most likely for quite a while, and then we started to tire a little bit. We had a couple with cramp and we had to make changes and in that little spell we were punished for a couple of things that can happen at Premier League level.

"It’s a tough one to take on the chin, because a lot of me really enjoyed what the group gave today but it wasn’t enough for the fans in the end. The supporters will be frustrated at the moment, of course, because we’re in a run where it’s tough for us to win games, but they saw from the group, there was a lot of effort, a lot of quality, good understanding, even after going 2-1 down, we had a good few chances to score again.

"Lots there that stand us in good stead, but as we know, the Premier League is ruthless and we need to find a way to get some results.

"That was close to being our best today. Of course, there's a few little bits that we could tidy up on, but we've gone up against a side who have spent an awful lot of money and were in the Champions League last season, and we didn't look like a lesser side.

“That takes a lot of doing against Newcastle, because there's not many teams that go out against them and just go toe-to-toe and have a real good game, and, in my opinion, looks slightly more likely to score than they do."
