Arsenal boss Arsene Wenger has warned his players that they will need to work hard in order to prevent a cup upset against Brighton & Hove Albion this weekend.
The Gunners meet the Seagulls in the fourth round of the FA showpiece at the American Express Community Stadium, with Wenger providing a reminder to his stars that the Championship side will be no pushovers.
"We have to keep their strikers quiet," said Wenger, according to The FA's official website.
"In the cup, you have to be ready from the start and people like that can always surprise you if you're not ready.
"It's always difficult in the Championship away from home. I remember it was a very difficult game two years ago against a team who were on the way up with Gus Poyet.
"We needed to dig deep to get out with a positive result."
Wenger's Arsenal side ended a nine-year silverware drought when they won the cup last year.
