Alexis Sanchez has taken to social media to issue a rallying cry ahead of Arsenal’s FA Cup fourth-round clash with Brighton and Hove Albion on Sunday.

The Gunners take on the Championship outfit looking to book their place in the fifth round, a day after the likes of Chelsea, Manchester City and Tottenham were all knocked out.

Liverpool and Manchester United were also both taken to replays by lower-league opposition.

Sanchez posted the video above on his Instagram account on Sunday morning and wrote: “Come on gunners, important game today …”

Manager Arsene Wenger confirmed last week that German World Cup winner Mesut Ozil is set to star the game after his lengthy lay-off with a knee injury.

Also set to feature is Theo Walcott, who is edging his way back to full fitness after his own knee problem.

Arsenal, who are in fifth place in the table, host Aston Villa at Emirates Stadium in the Premier League next weekend after their FA Cup clash in Brighton.
