Roberto De Zerbi is surprised his skipper has never signed for a bigger club.

Lewis Dunk makes his 400th appearance for Albion when they face Stoke City tomorrow.

He made his Seagulls debut in a League One game MK Dons at the end of the 2009-10 season.

Albion boss De Zerbi said: “For me it’s difficult to understand how he has never played for a big team in the Premier League.

“If you ask me what I think about Dunk, I think he’s one of the best centre-backs in the Premier League.

“This is my opinion but I know well his potential, his standard of performances.”
