This is the first league meeting between the sides since February 1983 – Arsenal won 3-1 at Highbury with goals from Graham Rix and a brace from Raphael Meade.
The Gunners have won their last four matches against Brighton in all competitions, with three of those last four wins coming in the FA Cup, most recently a 3-2 win in January 2015 at the Amex.
Brighton have never won an away match at Arsenal in all competitions in six attempts (D1 L5), scoring just one goal in those six matches.
Arsenal are unbeaten in their last 31 Premier League matches against newly promoted sides (W26 D5), collecting 83 points from a possible 93, since losing 1-2 to QPR in March 2012.
Indeed, the last newly promoted side to win at the Emirates in the Premier League were Newcastle in November 2010 – then managed by current Brighton boss Chris Hughton.
Arsenal haven’t lost a home Premier League match in the month of October since 2002; a 1-2 defeat to Blackburn – since then, they’re unbeaten in 26 matches in the month (W21 D5).
49% of Brighton’s shots this season have come from outside the box (27/55); a league-high proportion.
Arsene Wenger has currently won a Premier League game against 44 different teams – level with Sir Alex Ferguson. If he wins this match, Brighton will be the 45th different club he’s defeated in the competition and it would be an outright Premier League record for a manager.
Alexandre Lacazette has scored in each of his opening three league appearances for Arsenal at home – the last player to do this in his first four home league games for the club was Jackie Henderson in 1958 (scored in first five).
Theo Walcott has scored in Arsenal’s last two matches against Brighton, netting a goal in each of their FA Cup victories in January 2013 and January 2015.
