So we have been here before. Actually, we've been here for a few times.
So we have been here before. Actually, we've been here for a few times. But I wasn't around when Brighton and Hove Albion took on Arsenal 80 years ago.
This weekend, a sell-out crowd will be able to savour the game once again. Both teams are on a relative high - with the Gunners beating Manchester City at the weekend, and the Albion on the back of one of the best performances of the season, with victory over Ipswich in midweek.
There are just a couple of players remaining in the Albion side from when the two teams met, also in the FA Cup, in January 2013.
So are the teams stronger than two years ago? The Gunners have strength right through the team, but Alexis Sanchez has been a joy to watch in the Premier League. He also has so much energy that teammate Theo Walcott described him as a Durcacell bunny.
As for the Seagulls, well I think it's fair to say they aren't quite the same team. Leo Ulloa announced his arrival in the UK with a goal on his debut and the Albion were close to forcing a replay.
Although the odds are stacked against Chris Hughton's side, if they show the same quality and determination as Wednesday night they could pull off an upset.
Wenger is likely to make changes and Hughton's players will want to show they can cut the mustard against top internationals.
Albion's experiences over the last few years against Premier League opposition has been mixed. Newcastle were overturned but nowhere near full strength, but the Seagulls enjoyed excellent performances against Sunderland and Liverpool in the League Cup.
This season's campaigning in that competition came to an end at White Hart Lane. Perhaps this rejuvenated side can go one better against Spurs' North London rivals? It should be fun.
