Brighton boss Roberto de Zerbi expects a battle against Burnley on Saturday.
The Clarets remain hopeful of staying up.
De Zerbi said: "They are fighting and they are playing very well.
"They're a lively team with a clear style of play and are aggressive with and without the ball.
"They have good players and know what they have to do on the pitch."
He continued: "The Premier League is the most difficult challenge in football, especially if you have young players and a young team.
"It isn't the same as leagues in other countries and it's tough because every game you have to push."
