The 21-year-old admits he is unhappy with his lack of first team action at the Eredivisie giants.
“I turned 21 earlier this month and I really want to play regular first team football. I’d prefer to stay at Feyenoord and get more playing time here, but I might have to move on if my situation doesn’t change,” said Mulder to Sportweek.
“My current contract is due to expire in the summer of 2011 and it’s in nobody’s interest if I warm the bench at Feyenoord for another season. It’s not like I’m determined to leave the club, but it’s not a certainty that I will stay either.
“I will certainly think about it if an Eredivisie club wants to loan me or buy me next summer. I have to think about all the pros and cons of leaving Feyenoord. I can’t rule anything out at the moment.”
