Chelsea are now in pursuit of AZ Alkmaar striker Moussa Dembele.
The 21-year old is already being targeted by Genoa, Juventus, Fiorentina and Sevilla with the Blues jumping i the queue to win his services.
Alkmaar technical director Marcel Brands revealed Chelsea's interest in Dembele.
"I know through his agent that Chelsea are following Moussa," Brands told De Telegraaf.
"But Genoa registered their interest a few weeks ago.
"I will certainly not say no to a transfer, but if there is nothing by 22nd June he will report for the club's first training session of pre-season."
