Mathieu Flamini is relishing life as a makeshift left back and as he prepares to face Manchester United's Cristiano Ronaldo on Sunday, the Frenchman insists he holds no worries.
Injuries to regular full backs Ashley Cole and Gael Clichy saw Arsene Wenger surprisingly hand the position to Flamini in mid-February.
As a right-footed midfielder Flamini was not the obvious choice but previously a bit part-time, the 22-year-old has now established himself as a more than accomplished defender.
In the UEFA Champions League in particular Flamini has excelled and having got the better of the likes of David Beckham and Mauro Camoranesi, Ronaldo is not a name that fills him with dread.
''I have come up against big players before and I've been okay,'' Flamini told the Daily Mail.
''Ronaldo is a big player but like I said, I have played against big players before.
''We will see. I do not worry. Even if I am about to come up against the best player in the world it doesn't even enter my mind.
''It was not easy playing in the role at first, I admit that. But at the same time I haven't surprised myself, in that it has gone well for me.''
With Cole persistently linked with a switch across the capital to Chelsea, Flamini could soon find himself a permanent fixture at left back but he insists it will remain the decision of Wenger and his alone.
''We will see,'' he concluded. ''I know Ashley is a big player and my natural position is midfield.
''But the coach will make up his mind on that one. It is up to him.
''At this moment I am happy to stay there for the team.''
