Juventus want 7.5 million euros, Inter want to offer 5.5 million euros, Gazzetta dello sport reports how the problem for Isla is to be solved:

“The distance between the clubs remain the same, because Juventus paid 9 million euros for 50% of the player this season and Inter see Isla as a good player. However his recent injury must be kept in mind. How a deal could be done as fast as possible for Inter? By insisting on paying at most 6 million euros(with bonuses) and putting a lot of weight on the fact that the player wants Inter.”
