Bristol City and Nottingham Forest fought out a goalless FA Cup draw and will replay their fourth-round tie at the City Ground.

Forest will be glad to avoid the fate West Ham suffered in the third round at Ashton Gate when the Sky Bet Championship side produced a memorable upset against Premier League opposition.

But Nuno Espirito Santo’s side will not welcome the extra game amid their battle to stay in the top flight.

Forest shaded the clearest openings during what was a pretty even affair but, in the end, had to settle for a rematch and the first clean sheet of Nuno’s seven-game reign.

City – 13th in the Championship and 17 places below Forest in the football pyramid – fielded 10 of the team that started the West Ham win, with Jason Knight replacing Joe Williams in the Robins’ midfield.

Forest were unchanged from the side that lost a five-goal Premier League thriller at Brentford last weekend.

There was heartening news on the bench as the influential Morgan Gibbs-White returned following a two-game injury lay-off, and the England Under-21 international came on at half-time to good effect.

City, roared on by another capacity crowd, began on the front foot and Tommy Conway was snuffed out twice by Andrew Omobamidele.

Conway was the hero against the Hammers, scoring in both games, but the young striker missed the target from 10 yards when unmarked, side-footing Anis Mehmeti’s cross wide.

Forest had carried little attacking threat in the opening quarter, apart from Nuno Tavares curling a free-kick in to the side-netting.

But the visitors did force the only save of the first half after 28 minutes, with Ryan Yates firing straight at Max O’Leary in the home goal.

City continued to probe but were almost caught by a swift raid moments before the interval.

Chris Wood led the breakout and fed Callum Hudson-Odoi, who pulled the ball back for the onrushing Danilo to hit the hoarding behind the goal.

Knight headed over Taylor Gardner-Hickman’s corner in first-half stoppage time, but Gibbs-White’s arrival gave Forest more fluidity when building attacks.

Gibbs-White almost made an instant impact with a header that was blocked and it was the midfielder’s lofted pass which saw Wood nod tamely at O’Leary.

City responded with Cameron Pring crossing to the far post and Forest goalkeeper Matt Turner shovelling the ball behind under pressure from Knight.

Robins substitute Sam Bell saw Murillo’s midriff get in the way of a powerful attempt, while Hudson-Odoi should have done better than find the side-netting after Gibbs-White had driven at the heart of the home defence.

When Pring ended a swift City counter-attack by rippling the side-netting and Danilo fluffed his line from a free-kick, the tie was destined to be replayed.

Liam Manning joked that he had aged ten years watching his City team defend for their lives to beat impressive Sunderland in the Sky Bet Championship.

Tommy Conway’s 20th-minute penalty, after Taylor Gardner-Hickman was tripped by Sunderland goalkeeper Anthony Patterson, proved enough to settle a hugely competitive game at Ashton Gate.

Play-off hopefuls Sunderland dominated for long periods of the second half but could find no way past inspired City keeper Max O’Leary, who made brilliant saves to keep out two Luke O’Nien headers and one from substitute Jobe Bellingham.

Head coach Manning said: “Max was outstanding, not just with his saves but the composure he showed under pressure.

“I’ve aged 10 years watching the game but I’m delighted for the lads because of the togetherness and spirit they showed.

“We have played better, but despite defending for long periods we were always a threat and had chances to extend the lead.

“I have a terrific group of players and, while there is room for them to develop, they lack nothing in effort.

“In a tough league like the Championship, you cannot afford to get too high when you win or too down when you lose.

“What the fans want to see above all is a team putting bodies on the line and giving 100 per cent. There could be no complaints on that score today.

“The commitment to block shots and stop crosses was fantastic. It had to be because Sunderland played well, particularly in the second half.

“Still, I felt we were always capable of catching them on the break. Anis Mehmeti has hit a post and Harry Cornick was through on goal after going on as a substitute.”

Sunderland were caught playing out from the back for the penalty, having survived a previous scare doing the same, and interim coach Mike Dodds was understandably frustrated.

“My anger is mainly directed at a mad 15 minutes in the first half when we invited Bristol City to take the lead,” he said.

“Apart from the penalty incident, there were three or four other lapses that went unpunished and it gave them impetus.

“If I had seen that sort of sloppiness in training, the players concerned wouldn’t have been in the team.

“I haven’t seen it from the team before and don’t want to again. There were words spoken about it at half-time.

“We completely controlled the second half and created chances without taking them. I can live with that, but what happened in the first half was unacceptable.

“Their keeper has made some good saves, but at times our finishing could have been better.”

Of his own situation, Dodds added: “The club have been great in communicating with me and the ball is firmly in their court over what happens next.

“Whoever becomes the next head coach will inherit a fantastic dressing room at a club definitely on the up.”

The hosts hit a post in the first half through Mehmeti’s curling shot but had to survive several Sunderland penalty appeals during a backs-to-the-wall second half.

Playing towards their 2,600 travelling fans, the visitors applied constant pressure, only to be denied by O’Leary and some committed last-ditch defending.

Cornick had a great chance to settle the outcome when breaking clear, but the hosts were hanging on at the end before celebrating three hard-earned points.

Liam Manning admitted a cool exterior belied a racing heartbeat after his first home game as Bristol City head coach produced a 3-2 Championship victory from a five-goal thriller.

The Robins looked on course for a comfortable win when Taylor Gardner-Hickman curled a superb first goal for the club after 37 minutes and Tommy Conway doubled the advantage with a penalty just before the break after Matty James had been fouled.

But Boro roared back to level by the 52nd minute through Zak Vyner’s headed own goal and a Matt Crooks shot before Mark Sykes volleyed home a 67th-minute winner from an acute angle.

Manning punched the air at the final whistle, having taken four points from his first two games as successor to Nigel Pearson.

“That was nice and relaxing,” he joked after being asked to evaluate his first game in charge at Ashton Gate.

“There are less stressful ways to spend a Saturday afternoon and my heart is still racing. But I consider myself in a privileged position as head coach of a great club.

“Overall I’m delighted. The second half didn’t start as we had planned, but we will learn from that and the way the players defended the lead after going 3-2 up was fantastic.

“We worked in training on four of the lads defending against eight attackers and it was a bit like that in the closing stages when every player had to show great commitment.

“The most positive sign was the number of quality chances we created against a very good side. The crowd played their part and I felt very proud to be on the touchline at Ashton Gate in charge of a Bristol City team.

“You never stop learning in this game and if you think you know it all, you shouldn’t be involved.

“I have great faith in the squad I have inherited and we have a lot of young players who will improve with age and experience.”

Boro boss Michael Carrick sent his side out early for the second half, but made it clear there were no teacups thrown during the interval.

He said: “I just told the players to believe in what they are good at. Do what they do best. In the second half we were more like our usual selves.

“We controlled the game for long periods so I’m very disappointed to be going home with nothing.

“I didn’t think it was a penalty because our player got a touch on the ball, but that’s football.

“We paid for a messy five minutes in the first half and one in the second. Other than that, we played some good stuff.

“When those little moments catch you out, you can find yourselves with too much to do.

“The boys were good chasing the game in the second half and then one lapse has cost us.

“All their goals came from isolated incidents. First a shot into the top corner no goalkeeper would have saved, then a penalty and then a corner.

“We didn’t manage the minutes leading up to half-time well enough. But the players responded really well after the break and we looked the only team likely to win.

“Bristol City were well organised and asked questions of us. I wish Liam all the best in his new job.”
