Arsenal star Mathieu Flamini admits he was not happy when first being asked to play at left back by Arsene Wenger.
The 22-year-old midfielder was brought to Highbury from Marseille, and thought his future was in the centre of the park for The Gunners.
However, due to injuries Flamini was switched to left back, and he has excelled despite playing out of position.
Flamini has been part of Arsenal's defiant rearguard, which has been the catalyst for their UEFA Champions League assault.
Another clean sheet in Villarreal on Tuesday will put them in the final, and Flamini cannot believe how things have turned out with him playing in such an unfamiliar position.
"The French education is one of the best," Flamini told L'Equipe. "I took advantage of it at l'OM.
"Then, when you decide to leave between 18 and 24, you have to play and have fun playing. If not, you are wasting your time.
"I would never leave for anywhere. At Arsenal, a very big club, I knew there was a very great manager, Arsene Wenger, who uses youngsters when they deserve it.
"The first time Mr Wenger asked me to play at left full back in a training session, I was very surprised.
"I made him repeat 'Me, coach?' To be honest, I was not very happy, but the team was decimated in defence, and the group's interest is the most important.
"Moreover in modern football, a good player has to be able to adapt.
"It is not that easy when you have a real winger in front of you. But I try to do my best, at first remaining very vigilant."
