Brighton caretaker manager Andrew Crofts isn't surprised seeing Graham Potter leave for Chelsea.
Crofts has stepped up from his U21 coaching role to replace Potter.
He said, "It's a reflection of him to see where he has taken the club from, to where we are now, that has generated interest from big clubs.
"Since he's come into the building, what he has created with the staff, the players and everyone has been unique. It just gives the club such a good platform to build on.
"On behalf of everyone at the club we wish him all the best in his next chapter alongside the members of staff that will be joining him there."
