Everton defender John Heitinga is unhappy with the lack of first-team action at Goodison Park, according to his agent.
The Dutch international has started just eight of the Toffees' 19 Premier League games this season, with David Moyes preferring Sylvain Distin in the heart of his defence.
Rob Jansen, Heitinga's representative, revealed that his client would be willing to listen to offers from elsewhere should the current situation continue.
"Heitinga is definitely not happy with what is happening at Everton and we don't hide that," Jansen told VI Radio. "He is looking at a solution.
"When an appropriate situation arises for a transfer, we will certainly not ignore it."
The 29-year-old, who was voted Everton's player of the year last year, joined the club from Atletico Madrid in 2009.
