Antony spoke to ESPN Brazil, accepting responsibility for his dream move to the English side not working out but also lamenting the treatment towards him at the club.
"I'm not the kind of guy who gets involved in controversies, who names people, in fact, I won't mention anyone's name here," said Antony.
"But I think there was a bit of a lack of respect there, even a bit of rudeness too, with no one giving you a 'good morning', a 'good afternoon'. Not even that. But, anyway, that is in the past, I won't give much importance to these things.
