Richard N: Either Arsenal will score a quick double in the next 10 - 15 mins or Hull will keep them at bay and grab a late winner. Maybe.

Andre Gwilliam: Eldin Jakupović stop it!!! Stop saving these shots. It's annoying me... oh man.

Rich: I wonder if Wenger will still support FA Cup replays if this one remains goalless?

Alexis Sanchez springs the ball over the top of the penalty area and Laurent Koscielny can't quite get a head on it. 

Arsenal continue to press and Sanchez has a go - this time from the left - but it goes high and very wide. 

What a save this was!

Take a look at the best moment of the game for Arsenal - Joel Campbell's effort earlier in the half brilliantly saved by Hull keeper Eldin Jakupovic.

Shadrack. A Mwamburi: Typical Arsenal. No one wants to shoot.

Samoalfred: So Arsenal can't score against a second string Hull City side in over an hour of play?

A rare break forward for Hull. 

Nick Powell feeds to David Meyler and the Tigers captain strikes the side-netting. 

Another change for Arsenal as Alex Oxlade-Chamberlain comes on for Alex Iwobi. The Gunners are going for this now....

"How often have Hull been into the opposition half in this half? Ospina has hardly had a touch since the break."

Corner to Arsenal. Theo Walcott whips it in and Mohamed Elneny looks like he's going to have a go from distance.

He does, but the Egyptian skies it.

Substitute Olivier Giroud gets in on the action. He weaves his way past the Hull defenders but can only shoot at the keeper.

Watford make six changes, with goalkeeper Costel Pantilimon among those coming into the side. Just the one change for Leeds - defender Sol Bamba for the injured Liam Cooper.

Watford XI: Pantilimon; Paredes, Britos, Cathcart, Holebas; Capoue, Suárez, Watson; Abdi, Deeney; Amrabat.  

Subs: Gomes, Nyom, Prödl, Behrami, Guedioura, Anya, Ighalo.

Arsenal are pressing and pressing, passing and passing. But still they can't get the ball in the net.

Time for re-enforcements: Alexis Sanchez and Olivier Giroud come on for Joel Campbell and Danny Welbeck.

"That's a quality save - absolutely different class there and exactly why the manager sticks with Jakupovic"

Another cracker of a save from Hull goalkeeper Eldin Jakupovic.

The man in green stretches wide to palm away Danny Welbeck's in-swinging effort. 

We've got an injury. Nick Powell is down on his knees after a trip from Mathieu Flamini.

The Hull forward gingerly gets back up again and shoots a nasty stare at the Arsenal offender.

Vince: This seems to have 'late Hull Cup shock' written all over it. Arsenal need to score quickly.

Gil Lau: There's got to be a goal for Arsenal in this game somewhere!

It's all gone a bit limp since Joel Campbell hit the post for Arsenal.

The hosts have a corner, from Campbell, and after knocking the ball around the box it eventually goes out for a free-kick. 

Moses Odubajo comes on for young defender Josh Tymon.

And, as predicted, Tom Huddlestone replaces Ryan Taylor for Hull.

"Everything is still in Arsenal's favour just now, but you never can tell."

Arsenal free-kick on the edge of the area. Joel Campbell whips it in and it hits the post! So close!.

Looks like Eldin Jakupovic got the slightest hand to it. What a save.

Another penalty shout for Arsenal. Calum Chambers is clattered in the box but Mike Dean once again waves play on. 

And Alex Iwobi does just that. The youngster lets fly from distance and his shot goes just wide of the post.

Tom Huddlestone is warming up and receiving instructions from the Hull bench. Looks like manager Steve Bruce is going to make an early change to try and mix things up.
