Juventus are believed to be concerned that the sale of Barcelona forward Neymar to PSG could mean that Barcelona pursue Paulo Dybala.
Reports in Italy - via Sport - claim that the Blaugrana would use the €222m brought in from the potential sale of Neymar to launch a big money move for the Argentine forward.
And if Neymar does exit for France, Lionel Messi will reportedly request that Barcelona bring in his compatriot from Juventus.
Corriere Dello Sport reported on Tuesday that Barcelona have already seen a €95m bid for Dybala rejected by the Bianconeri.
Juventus reportedly deemed the huge offer insufficient and insisted that the former Palermo man is not for sale at any price.
The 23-year-old scored 19 times in all competitions last season, including a superb brace against the Catalan giants in the first-leg of their Champions League quarter-final clash.
The proposed €95m fee from Barcelona would fall just short of the £89m paid to Juventus by Manchester United for Paul Pogba last year.
Juventus' reluctance to sell despite the substantial fee could mean that Barcelona must wait until they receive the record smashing offer rumoured to be imminent from PSG.
The influx of money would allow Barcelona to launch an even more astronomical fee than the one previously rejected for Dybala.
