Lamptey, 20, has featured just 19 times for the Seagulls first-team since his €3-million switch from Chelsea but has already attracted the interest from Europe's elite.
Bayern Munich, Arsenal and Tottenham are all said to be monitoring his progress but after signing a new five-year deal this month, talk of his exit has been put on hold.
Former Premier League star Kevin Campbell believes Graham Potter's side secured his services on the long-term contract in order to get the best deal possible ahead of his inevitable exit.
"Brighton ain't stupid, they are making sure they have Lamptey secured to a long-term contract so anyone that wants to sign him have to pay accordingly. I am sure that is the case," Campbell told Football Insider.
"They took a chance when they signed him and he has exceeded expectations. He has now got a contract that he deserves and while it is great for him it also protects the football club.
"It is great business all round. He is definitely destined for one of the top six clubs in the future."
