Wales midfielder Joe Ledley could be tempted by a move abroad as he weighs up his career options this summer.
Ledley made nearly 100 appearances for Crystal Palace after joining from Celtic in January 2014.
But he was frozen out by then-Eagles boss Sam Allardyce during the second half of the 2016-17 season and released by the Premier League club last week.
"It's been frustrating," Ledley said after helping Wales to a 1-1 World Cup qualifying draw in Serbia on Sunday night.
"I don't know why I've not been even in the squads, but it was the decision of the manager and I had to deal with it and get on with it.
