Juventus director Giuseppe Marotta has told fans to be worried that coach Antonio Conte could decide to leave the club this summer.
The former Siena boss has won three Serie A titles during his three seasons in Turin and went unbeaten throughout his first season at the club.
However, he hinted recently that he would be open to offers from other clubs and Marotta is concerned that the 44-year-old could move on this summer.
"I think it's the right way to recognise the scope of what Conte has achieved at Juventus," he told reporters.
"As we've said before, Conte is a very well-prepared coach that has had a big say in the results achieved by this club.
"I believe it wise for the fans to worry about him being lured away from Turin."
Conte sat next to Sir Alex Ferguson during the Europa League final on Wednesday and Marotta has joked that the legendary Manchester United manager was giving advice to the Italian.
"Yesterday was a big celebration for football, the final of a very important trophy, it's always a social occasion where you can meet icons of the sport like Alex Ferguson," he added.
"Maybe Conte can get some football wisdom or some advice about his future as a manager."
