It may have been an honest mistake, but we are still going to make them regret it.

Albion will be looking to put Arsenal to the sword on Sunday after an ill-advised tweet left the Premier League team embarrassed.

The tweet was sent to all the clubs still in the draw for the FA Cup, but only Arsenal, West Ham, Birmingham, Cardiff, Middlesbrough and Chesterfield decided to make it public.

Mix up or not, never has there been a better time to make them eat their words.

Albion, under the guidance of Chris Hughton, are beginning to hit their straps with many calling the 3-2 triumph over Ipswich in midweek the best performance of the season.

Arsenal too have hit a bit of form, but there is something about the FA Cup which favours the underdog.

This already mouth-watering tie has just been kicked up a notch. Football fans are not the forgiving type, and if the romance of the cup is truly still alive, Arsenal supporters will be trudging back to the capital city with their tails between their legs come Sunday night.

They say beware of the wounded animal – and come Sunday the Seagulls will be gunning for a big scalp.
