Juventus are reportedly demanding that Barcelona include 17-year-old Ansu Fati in any deal to take Miralem Pjanic to Camp Nou when the transfer window reopens.
The Spanish champions are understood to have made Pjanic and Inter Milan forward Lautaro Martinez their top two targets this summer, and are willing to offload players in order to fund bids for the Serie A duo.
The prospect of swap deals has been raised, particularly given the financial impact of the coronavirus shutdown, and Barcelona are reportedly ready to include Arthur or Nelson Semedo as part of any agreement.
However, Todofichajes claims that Juventus have instead asked for Fati, who burst onto the scene at the start of this season.
Barcelona are not willing to offload one of their brightest prospects, though, and are understood to have ruled out the possibility of the attacker leaving the club.
Fati became the youngest ever Champions League goalscorer and Barcelona's youngest goalscorer in any competition earlier in the campaign, while he has scored five goals in 24 appearances across all competitions in 2019-20.
