It's unfortunate that Juventus lose 3-0 to Milan at home, it's clear they are struggling lot. At this point, CR7 will be playing Europa League Football next season. Juventus is really bad shape in this season. Juventus won't happy to participate in Europa, let's see they still have 3 matches left.
Unless, Europa League next season to CR7. It's really sad for CR7, time to leave Turin?
CR7 can stay in Juventus if the club manage to join Champions League. If they fail with this mission and have to play in Europa League, CR7 will leave because he is old enough and he won't have patience to waste a few last seasons in his career.
It is a sad ending that CR7 was signed as a core player to bring the Champions League to Juventus but after 3 seasons, they both failed, no trophy and even will be play in Europa League. Still have small hope but they will have to need luck of dropped points from other teams.
