The Brighton academy product has been at the centre of widespread speculation for weeks now, and it quickly became clear that it was a case of when, rather than if, he would make a move to the capital.
A fee of around £50 million is understood to have been enough to secure the deal, but even with that handsome compensation in their back pocket, Albion are likely to miss the defender, who played his way into England’s Euro 2020 squad last season.
Head coach Graham Potter said, “Ben has come an incredible way in a short period of time, but we felt he had all the attributes to achieve what he has in the past few years.
“From the loan spells with Newport, Peterborough and Leeds through to his debut season in the Premier League with us last season, Ben has acquitted himself with great professional at every step of the process.
“We are incredibly proud of him and what he has achieved, and much credit must go to our academy, who have played such an important role in developing Ben from a younger age.
“On behalf of everyone at the Albion, I would like to thank him for his contribution to the club, he has been a pleasure to work with ever since I arrived here, and wish him well for the future.”
