Manchester City, Tottenham and Newcastle have been warned they will have to stump up £8 million if they are to sign Gil Vicente defender Pecks.
The three Premier League club's are desperate to improve their defensive options, however Gil Vicente president Antonio Fiusa has stated that any interested parties must pay the buy-out clause for the 20-year-old.
Cape Verde international is known for his commanding tough-tackling style playing in the centre-back role, and could make a move to one of the Premier League big-boys in the near future.
And, when discussing the future of his star, Antonio Fiusa told reporters: “The player has a contract until 2017 and we do not have to sell at an inferior price."
Manuel Pellegrini seems to determined to add to his defensive line, with the club over relying on the fitness of club-captain Vincent Kompany.
Meanwhile, Spurs boss Andre Villas-Boas, who could also make a move for the star, is expected to spend more money once the January transfer window opens.
