Thomas Vermaelen has revealed his frustration at having to fill in at left-back for Arsenal as he doesn't see it as his best position.
Gunners boss Arsene Wenger has turned to Vermaelen in recent weeks to do a job for the side due to injuries to regular full-back Kieran Gibbs and Andre Santos.
The Belgian international is widely regarded as the club's best centre-back and while he understands the reasons behind Wenger's request to perform in a different role, he admits he would rather be in the middle.
Vermaelen goes on to say that his patience is wearing thin at the Frenchman's continued policy of using Laurent Koscielny and Per Mertesacker in the heart of Arsenal's defence and he can't wait for the situation to change.
The 26-year-old told The People: "I am fed up playing at left-back. I don't think I am good there - I want to achieve my highest level and I can't do that on the left.
"I play there to help the team but it gives me no satisfaction as I can't reach my best standard.
"I do my job but seldom feel content after matches. If the team wins I am happy, but it remains frustrating."
Vermaelen has also spoken of his disappointment at losing the Belgium captaincy to Manchester City defender Vincent Kompany.
"I'm not happy about it," said Vermaelen, who moved to Arsenal from Ajax in 2009. I was proud to wear the armband."
