Newcastle United manager Steve Bruce along with his son Alex, watched Crew Alexandra played to a 2-0 win over Peterborough United on Sunday afternoon.
Dembele has registered five goals and four assists in ten appearances across all competitions for The Posh in the ongoing season.
Dembele who was born London is eligible to pledge allegiance to England, Scotland and Ivory Coast.
However, despite the interest in the youngster, the club's Director of Football, Barry Fry has told his suitors that they have no interest in selling him despite the numerous offers coming to their table.
“We have no interest in selling Siriki,” Fry said. “We’ve had bids for him, but they’ve all been rejected, because the manager, the co-owners and myself agreed we’d not sell another player after Toney.”
It remains to see how far the interest will go from the Magpies ahead of the January transfer window.
