Welcome to our LIVE coverage of Brighton and Hove Albion's FA Cup fourth round match against Arsenal.

Barnes has a chance to slip in Ulloa but can't quite get the pass right.

Dicker with a decent cross field ball but LuaLua can control down the left – still probably finding the pace of the game.

Lovely close control from Ulloa and Diaby has to foul him. Brighton fans liking the look of their new boy.

Santos gets forward but his cross was poor. Arsenal will be hoping for better from him at both ends in the second half.

Wilshere, Walcott, Cazorla, Arshavin – plenty of options on the bench for Arsenal if they want to chase a goal.

Wojciech Szczesny has to deal with a tricky back pass straight away. I'm sure he was delighted with that!

Brighton forced into a second change at half-time. Will Buckley is off and Kazenga LuaLua has come on.

Rosicky drags a poor effort wide and that is the last bit of action in the half. Entertaining first-half – still all to play for.

Brighton with a counter attack and they have men forward but Dicker's ball is disappointing.

Andre Santos tries a miracle shot from distance and it is a woeful effort that goes miles over and wide too.

We will have three extra-minutes. Buckley needs some treatment now.

Ball goes off Lopez for another Arsenal corner. The home fans think it went off Ramsey last but that looked to be the right decision to me.

Giroud goes down on the edge of the area after it looks like he is sandwiched but it is the French striker who gets charged with the foul.

Bridcutt with a clever looking ball forward but Koscielny steps up well to cut it out.

Jenkinson whips in good cross and Calderon has to head clear. Arsenal have been dangerous down the right.

Arsenal having plenty of corners but Brighton have defended them well. Ulloa back to clear the latest one from Oxlade-Chamberlain.

Calerdon has moved to centre-back, Lopez is now right-back and Dicker has gone into midfield.

Greer's afternoon is over – looks like he did his hamstring – on comes Dicker.

Delay in the match as Gordon Greer needs treatment – his afternoon could be over too.

Buckley now cuts inside and gets a shot on target – no power on it though so Szczesny can gather.

BUT NOW BRIGHTON ARE LEVEL!!! Mistake from Szczesny as he allows Ashley Barnes to get in front of him and head home from a corner. Shocking defending from Arsenal and poor from the Polish keeper.
