Johan Djourou admits the time may have come to leave Arsenal after becoming frustrated by his lack of opportunities.
The Switzerland international started just 14 Premier League games in 2011-12, even having to fill in at right-back rather than his favoured central role.
The 25-year-old only signed a new contract at the Emirates Stadium in February, committing himself to the club until 2015.
As a result, he could be forced to seek a loan exit as he goes in search of games with the likes of Thomas Vermaelen, Laurent Koscielny and Per Mertesacker ahead of him in the queue at Arsenal.
"My situation at Arsenal is not easy," Djourou told Swiss website 20 Minuten. "I've never played so little and especially not in my own position. If an interesting offer comes, I'll look at it carefully."
Further pressure is being heaped on the player by his national team coach, who insists Djourou must be playing for his club if he is to remain a part of the Swiss set-up.
Switzerland boss Ottmar Hitzfeld said: "If he wants to be selected, he must have some game time in the club. This is not the case at Arsenal."
Arsene Wenger is likely to be unwilling to allow Djourou to leave as he will want to keep four centre-backs within his first-team squad.
