Arsenal boss Arsene Wenger has warned his side against complacency ahead of Sunday's FA Cup clash with Championship side Brighton.
The Seagulls have struggled this season and they are currently 19th in the Championship table, but they have improved since the arrival of Chris Hughton as manager with three wins in four games since the former Norwich boss took charge.
Arsenal beat Brighton 3-2 in the FA Cup two years ago, and Wenger doesn't expect Sunday's foruth round tie to be a straightforward affair for his Gunners side.
He told the club's official website: "We have to keep their strikers quiet. In the cup, you have to be ready from the start on 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.
"Chris Hughton will give them his experience and his competence, of course. He knows how to prepare a team for a challenge like this. For us the challenge is to turn up with the same spirit and show that we can be consistent with our attitude game by game.
"In the FA Cup, god knows that is needed. We know that it will be another big challenge for us to go there and come home with a positive result."
Wenger also revealed that German playmaker Mesut Ozil is likely to start at the Amex Stadium on Sunday and Arsenal are expected to field a strong starting line-up as they continue their FA Cup defence.
Arsenal are 1/1 to win Sunday's clash and 1/1 to win 3-1, while the Gunners are 1/1 to win the FA Cup outright.
