I don't think it will be that easy, even if it succeeds in removing the defibrillator but still, Inter will still fight even harder to convince Eriksen that Eriksen can actually return to play safely. Imo, Eriksen still needs time to return to play or sad news may come about his career, because Eriksen's arrival back to Inter is not for training sessions but to talk about whether his career will continue or not. Well, I personally still hope that Eriksen can recover and be 100% healthy again, but if I consider from some of his progress so far it seems that Eriksen's permission to be able to return to play may be very difficult.
He will have to consider what is more precious with him and his family. Football, his career or his lovely family. He will never know what will happen if he continues his career. Even medical doctors tell him it is safe enough, there will be risk that nobody knows ahead of time.
Before his horrific accident in Euro, he has a good health record.
I'm not an Inter Milan fan, but for Eriksen, I also wish the same thing. He is too young to retire. He still has a chance to feel the champion with his club. if indeed Eriksen decides to retire, I hope, in the future he can still coach the club and become a successful coach by awarding trophies.
He can play but not in Italy. As I know, Italy don't allow sport athletics includes football players who have serious cardiovascular problems to play. Eriksen can not play in Premier League as well. I think he can return to Ajax Amsterdam and continue his career there.
