Gervinho has suggested that Arsene Wenger's lack of faith in him prevented him from succeeding at Arsenal.
The Ivory Coast international had a torrid two years at the Emirates Stadium, eventually leaving for AS Roma last summer in an £8 million deal. The clumsy winger became somewhat of a laughing stock at Arsenal, but has turned his form around under Rudi Garcia.
Having left Arsenal with his confidence at rock bottom, plenty of Arsenal fans were happy to see Wenger cash in on the fallen star. However, Gervinho is refinding the form that convinced the Frenchman to fork out a reported £11 million to sign him from Lille in 2011.
Gervinho scored nine and assisted ten goals for Roma last term, helping them to a record points tally and an impressive second-placed finish in Serie A behind a formidable Juventus.
Gervinho will return to England for the first time since leaving Arsenal on Tuesday night to take on Premier League champions Manchester City. The 27-year-old will undoubtedly be keen to show Arsenal what they are missing.
However, he believes that he has nothing to prove returning to England and insists the only reason he didn't hit his best form as a Gunner was because Wenger did not have the confidence in him.
Speaking ahead of the Champions League tie at the Etihad, Gervinho said: "I feel like a new player in Italy. It is very hard to have confidence in yourself when the coach does not have confidence in you - and it's clear at Arsenal that confidence was not shown in me.
"At Roma the coach and the staff showed confidence in me from the first day - and because of that I have been able to show exactly what I am capable of.
"I don't feel like I have anything to prove in England. I think the proof of what I can do is shown by a coach that has confidence in me.
"Maybe Arsenal now think they should have shown more confidence in me - but that is not my problem. All my concentration is on a successful season with Roma."
Roma go into the game against the Citizens as firm underdogs. Despite their impressive showing in Serie A, their lack of presence in European football placed them in the fourth pot of the Champions League draw.
Manuel Pellegrini would have preferred to avoid the Rome club, however, and Gervinho believes their lowly status should not rule them out of competing with Manchester City.
"I can't think of any good reason why we should be scared of Manchester City - I don't see why we should fear Bayern Munich either," said Gervinho.
"The way we are playing this season - there is no reason to think we can't beat anybody. The only team that we need to concentrate or think about is ourselves.
