I see from stats Arsenal have not managed to keep a clean sheet in their last 7 FA Cup games away from home, conceding 12 goals.
That is a worry, and to be honest I see them conceding here. The difference will be the Arsenal offence, which is capable, on their day, of blowing away any team.
Indeed, Arsenal roared back at Reading and scored 7 to win comfortably despite conceding 5. They hammered West Ham 5-1 on the weekend, and of course have already banged 6 past Southampton and 7 past Newcastle. On their day, if things click, they are untouchable. Thing is, will they do it here in a game Brighton will be more than ready for?
I think Brighton would love a money spinning replay if possible, because I genuinely do not see them winning (yes, even when I take off my Gooner glasses).
I think Wenger is desperate for a trophy and with the team trailing the top 4 in the league he does not need another replay. This has to be a win and it has to come in this game. Expect a strong performance, especially in the 2nd half, where Arsenal have been doing well recently, even in losses.
