Roberto De Zerbi has revealed he expects to lose at least two of his Brighton stars this summer.
The move could see a summer transfer between Arsenal and Chelsea for impressive midfielder Moises Caicedo who is rated at £70m.
Seagulls boss De Zerbi said: “We will lose some players, maybe Caicedo or maybe Mac Allister.
“We need to bring in some other good players.”
Japanese winger Kaoru Mitoma and Ecuadorian left-back Pervis Estupinan have also caught the eye.
But De Zerbi said: “They need to stay with us. I don’t know if they’re ready to play with big teams.”
All four stars were involved in Brighton's 3-0 win over Arsenal, which may have all but sealed the destination of this season's title.
The defeat to De Zerbi's lively side means if Arsenal lose to Nottingham Forest on Saturday the title will be confirmed as Manchester City's.
However, a win for City against Chelsea will wrap up the title regardless.
In Brighton's case, they have moved up to sixth place, one point ahead of Tottenham and Aston Villa with two games in hand.
