The Gunners dominated proceedings for the majority of the match and had a good shout for a penalty turned down in the first half, but they couldn't find the crucial breakthrough, meaning there will be a replay to see who reaches the next round
Both sides rested plenty of first-team players—the hosts made nine changes while the visitors made 10—with 16-year-old James Tymon starting for Hull at left-back.
Arsenal came close early on through Mohamed Elneny when he was found on the edge of the penalty area from a corner. The Gunners were somewhat unlucky not to receive a penalty as Alex Bruce blocked the shot with his arm, but referee Mike Dean waved play on, per BT Sport Football:
The Gunners continued to press, and Danny Welbeck—starting his first match since April last year—headed straight at Jakupovic after some excellent work by Theo Walcott on the right. Welbeck also had a shot from a narrow angle saved soon after, while Alex Iwobi curled an effort just wide.
Football writer Miguel Delaney noted the hosts were dominating their opponents and praised Iwobi's performance:
Jakupovic was called into action again when Walcott drove a shot at goal from a similar angle to Welbeck's earlier strike.
Despite largely containing the Tigers inside their own half, the Gunners were unable to further trouble Hull's goal as they defended resiliently. The Hull Daily Mail's Phil Buckingham noted the visitors remained strong in spite of Arsenal's pressure:
Arsenal's dominance of possession continued unabated after the break, and less than two minutes into the second half, they came close again as Walcott's close-range shot was well saved.
Jakupovic then made another outstanding save to tip Joel Campbell's curling free-kick onto the post, per BT Sport Football:
The one-time Switzerland international was on hand again shortly after the hour mark to keep out Welbeck despite his shot deflecting off Curtis Davies.
The England striker was eventually substituted for Alexis Sanchez as Arsenal sought a winner, and he drew plaudits from ESPN FC's Mattias Karen:
Olivier Giroud was also thrown on and nearly had an immediate impact after smartly evading Davies, but the Frenchman's shot was a fairly tame effort and the in-form 'keeper dealt with it easily.
Meanwhile, a rare counter-attack for Hull resulted in David Meyler lashing the ball into the side netting after Nick Powell found him with a neat pass.
The Tigers came to life late on as they attempted to push forward with more regularity, and Sone Aluko tested David Ospina from 12 yards, but the forward was correctly flagged offside.
Arsenal were able to provide more tests for Jakupovic in the dying moments, but after saving well from Sanchez's free-kick, he calmly claimed the ball amid a scramble in the penalty area.
Neither side will be happy with the prospect of a replay, with Arsenal concentrating on the Premier League title race and the UEFA Champions League while Hull are chasing promotion from the Championship. ESPN FC's Dale Johnson noted the difficulty the FA faces in scheduling the replay due to the two sides' commitments and their inability to play on Champions League nights:
Arsenal would expect to win if they can put in a similar performance, but at the KC Stadium, Hull could easily prove a difficult obstacle to overcome, particularly if Jakupovic has another stellar day.
Per BBC Sport's Chris Osborne, both managers rued the need for a replay. Arsenal boss Arsene Wenger said:
The replay is not especially good news but Hull defended very well.
We were not incisive or accurate enough in our passing in the final third. As long as they did not concede, they maintained with how they played. We had 20 shots, 70 percent possession, but no goals.
I cannot influence the referee's decisions, only the technical quality of my team. If we have no injuries, we can cope with the fixtures.
I think FA Cup replays is a particularity of the English rules and you have to respect that.
Hull manager Steve Bruce added:
I don't know when we're going to play the replay. That's added to the fixture pile-up we've got.
We made 10 changes and we rode our luck a bit, but the team deserved it for the spirit and the 100 percent effort they gave. It bodes well when I see the strength in depth we've got, because we're going to need it.
