The situation appears to be that Inter value half of Mauricio Isla at 5 to 5.5 million euros whereas Juventus are firmly holding their ground and will not let their half go for below 7.5 million euros. 

In an interview with 24horas, Isla confirms that Inter have made an offer for his services.

"Yes, there is a possibility of leaving Juventus and Inter have made an offer for me. I only want to play and it would be perfect because I want to make myself useful, also for the national team, and want to find my form again."
