Newcastle full-back Davide Santon has promised there is more to come from him, but his agent has admitted he would be tempted by a move back to Serie A.
The 21-year-old Italian has established himself as Alan Pardew's first-choice left-back and is likely to line up there once again at Everton on Monday.
Santon, who joined Newcastle from Inter Milan last summer, admits he is still learning his trade in English football after a tough baptism last season.
He said: "Last season, the first few months were difficult for me because Serie A and the Premier League is totally different.
"But now I feel better on the pitch and more confident, so I am enjoying it.
"I want to help Newcastle keep improving, keep moving forward and be the best we can be.
"The fans have not seen the best of me yet, though. I can still do more, though, I can be much better - and I will improve while I am here.
"I am really enjoying it. I like Newcastle - I like the city and the people in it.
"The fans are brilliant, I like my team and I like the manager. Better than this is impossible!"
However, Santon's agent, Claudio Vigorelli, has been quoted in the Italian media, claiming there could be an interest from Roma.
"AS Roma might be interested in Davide, seeing that they rely on young players and have a coach good that will make them grow," he told Tuttomercatoweb.
"Santon is fine at Newcastle, but if Roma's interest was true, it would be a great opportunity for Davide."
Vigorelli also stated that he could not understand why Santon was being left out of Italy's Under-21 squad.
"I was surprised by the exclusion of Davide from Italy Under-21 squad," he said. "He plays as a regular in the Premier League, one of the top leagues in the world and he has proved to be one of the most reliable players.
"I hope that Davide can soon convince (Under-21 coach, Devis) Mangia and why not, (Italian National team coach) Cesare Prandelli."
