It is very strange, but 'TuttoSport' believes it could happen. Juventus are thinking of doing a swap with Barca including Busquets and Bonucci and one with Madrid including Asensio and Bentancur. This is as a result of the crisis there is in Turin.
There has been talk for a while of even Cristiano Ronaldo leaving the club. The fact Juventus have not been successful in the Champions League in the last three seasosn has affected the club's coffers. That is why they have come up with these drastic solutions.
Returning to Busquets, Bonucci, Asensio and Bentancur, Barca's new board led by Joan Laporta will have to weigh up whether the move would be beneficial both financially and on the sporting front. Getting rid of a player with a large salary will be good, but Bonucci will probably want a large wage as well.
On the Real Madrid swap, it seems unlikely to happen given the fact that Asensio is proving to be an important player for Zinedine Zidane.
