AZ Alkmaar have warned Chelsea that they will have to move quickly if they are to convince them to sell prize-asset Moussa Dembele.
Widespread reports have suggested the forward is high on new coach Carlo Ancelotti's wish-list, with the likes of Genoa, Juventus, Fiorentina and Sevilla also monitoring his situation with the Dutch champions.
AZ technical director Marcel Brands has stopped short of ruling out a potential sale in the summer, but has warned his club will not become embroiled in protracted negotiations.
Brands went on to reveal that Dembele's agent, Patrick Vervoort, has informed him of interest from Stamford Bridge.
"I know through his agent that Chelsea are following Moussa," said Brands in De Telegraaf.
"But Genoa registered their interest a few weeks ago.
"I will certainly not say no [to a move], but if there is nothing by 22nd June he will report for the club's first training session of pre-season."
Dembele has professed to being flattered by interest from overseas but insists he is more than happy with his current paymasters.
"I am certainly not against such a development," Dembele told Het Laatste Nieuws.
"I am indeed in a good position. I can continue at AZ, where it is excellent, or move to a foreign club."
