Fluminense midfielder Jean has refused to comment on whether he will be joining Roma in the summer.
The 26-year-old has been heavily linked with a transfer to the Giallorossi come the end of the season.
But the Brazil international has insisted that he is focused purely on his current club.
“Any negotiations are dealt with by my agent,” he told reporters in his home country.
“All I'm concerned with Fluminense – the rest I do not care about.
“It's pleasing to be linked with these clubs, but there are people who run my career – I don't do it directly.”
