Patrik Schick's dream move to Juventus could be on the rocks after problems arose in the negotiations between his current club Sampdoria and the Italian giants.
Sky Sports Italia has alleged that the transfer is being held up over problems between the two Serie A clubs, while La Gazzetta dello Sport has claimed that an issue with Schick's medical flagged up warning signs from Juventus' medical team.
Schick has already agreed personal terms with I Bianconeri over a switch to Turin, and underwent a medical with them during a break at the European Under-21 Championships in mid-June.
Juventus would likely want to walk away from the deal if the 21-year-old is thought to have an underlying medical condition or muscle problems from earlier in his career. Sampdoria, however, believe that the transfer should still go ahead as they consider Schick's potential contract with Juve to be valid.
Juventus are reported to have made a £20m offer for the striker's services in the close season, and I Blucerchiati were, despite not initially wanting to sell their star asset, eventually convinced to agree to accept the fee.
Schick, a Czech Republic national, only moved to Sampdoria from Sparta Prague in a £3.4m transfer last July, but his stock has risen considerably in the past 12 months thanks to his displays for the Stadio Luigi Ferraris-based side.
The forward netted 13 goals in 35 appearances for Marco Giampaolo's team last term , and his performances led to a number of European clubs - including Tottenham Hotspur and Internazionale - to send scouts to watch him in person.
It was Juventus, though, who made the first move to prise him away from the city of Genoa, and up until this latest development had seemed all but certain to add him to Massimiliano Allegri's first-team ranks.
It is now up for debate whether Juventus can reach a suitable compromise with Sampdoria to complete Schick's transfer in the near future.
