Three are clubs chasing the Argentine goalscorer
Juventus have received offers for star striker Paulo Dybala from Manchester City, Bayern Munich and Paris Saint Germain, according to Tuttosport.
There is a growing belief in Italy that Juve could be tempted to recoup a transfer fee of more than 100 million euros (£90m) for the 25-year-old.
It is believed the Turin club are currently ignoring the attention around their prize asset.
But talk of a summer sale with a fee similar to the one they earned for Paul Pogba from Manchester United in 2016 is growing.
Meanwhile, Juventus are stepping up plans to bring out-of-favour Real Madrid star Isco to Serie A, according to Tuttosport.
The Spaniard has struggled for regular time under Santiago Solari since the coach took charge in October and is thought to be frustrated with his current marginalisation.
Scudetto holders Juve fancy bringing him to the San Siro, to play alongside former Madrid team-mate Ronaldo, as the Turin club hunt both domestic and European glory.
