According to reports in Italy, Juve are preparing a proposal to the Old Trafford club.
Dybala is valued at €100m, whereas Manchester United have already told Inter they want €85m for Lukaku, so La Joya would move to England with a cash sum going to Turin too.
Maurizio Sarri has apparently given the all-clear to the switch, as he could use Lukaku as the centre-forward and return Cristiano Ronaldo to his more traditional wide left role.
At the same time, the Bianconeri would be putting a huge spanner in the works for their rivals Inter, who have openly courted Lukaku ever since Antonio Conte took over.
They are ready for a deal if Manchester united will give Lukaku and €15m.
