Gabigol is currently playing on-loan at Santos.
“I really liked the fans in Italy and my teammates were always very kind too. Even now on social media, fans keep asking me to return," he told Tribuna.
“It's hard to say what didn't work. Perhaps at that moment the team needed something different to what I could give. I played very little and only scored one goal."
Former Inter coach De Boer criticised Gabigol for his lack of effort in training.
“I respect De Boer a great deal and he was always kind to me. I think he was just letting off steam, or perhaps the message came through distorted here in Brazil. He knows more than me, so if he said those things, it means I have to improve and I consider it constructive criticism."
