Roma forward Gervinho believes coach Rudi Garcia is the reason in his upturn in form.
The former Arsenal attacker has been a key man for Roma this season and with eight goals in all competitions is the club's top scorer.
He netted twice in the first leg of Roma's 3-2 Coppa Italia semi-final win over Napoli on Wednesday and has hailed the influence of Garcia on his game.
Gervinho told Sports Illustrated: "The difference between Roma and Arsenal? The coach.
"Here my coach, Rudi Garcia, gives me confidence, I know that he believes in me. When I wake up in the morning, I like to come to work, I cannot wait."
The 26-year-old said he was not unhappy at Arsenal, but that playing regularly is essential in his development as a player.
"I could say that my success has been thanks to coming to Italy, but it is not so," he added.
"I am happy here, the city is fantastic, there are wonderful team-mates and friends alike, but many of these qualities were also in England.
"Life in Italy is the same as it was before me. What did I learn at Arsenal? Honestly, not much. It is difficult to learn anything on the sidelines.
"Why did I leave? Because I was not playing. Not enough. In Rome, however, it is another story."
