Brighton boss Roberto de Zerbi insists they're capable of beating Arsenal today.
Victory would end Arsenal's title challenge.
De Zerbi said: "Arsenal are a great team. They deserve to fight for the Premier League.
"I don't know who will win the Premier League but we have big respect for them. I think they are improving in a lot of things this year.
"They play fantastic football but I have to be focused on my team and think only about them as we have some problems.
"The last part of the season is very important for us and the club. We are still disappointed by the last result but I think on Sunday it will be a difficult game and we will be ready to try and win."
