Samir Nasri has been hugely impressed with Arsenal Football Club since joining them in the summer.
Although the Gunners have long been out of the race for the Premier League title, they will face Chelsea in the FA Cup semi-final if they beat Hull City.
And on Wednesday night they face Roma in Italy for a place in the last eight of the UEFA Champions League, with the Gunners leading 1-0 form the first leg.
"We have the quality to beat Roma. This season Arsenal are very, very strong," Nasri told L’Equipe. "We will not go to Roma looking to defend. We will go to win.
"We know we have to attack, while trying to ensure we keep things tight at the back. We know Roma will be fired up for the game, but we are confident in our ability.
"Theo (Walcott) is back, which is good. He will bring us pace on the wing. It is an additional weapon. It allows us to be unpredictable when we attack."
