Chelsea are making a play this week for Cagliari midfielder Godfred Donsah.
The young Ghanaian, who took part in the U20 World Cup earlier this summer, is a target also for Juventus, Fiorentina and Bologna.
Cagliari have confirmed an approach from Chelsea and coach Massimo Rastelli is concerned the talk is unsettling the youngster.
"Perhaps he hasn't the experience to handle such a situation," said Rastelli.
Chelsea are sending intermediaries to Sardinia in the next 48 hours to discuss a fee for Donsah.
