The 29-year-old, currently on loan to Benifca, is keeping his options open and refuses to rule out a move to either England or Spain.
“I am injured at the moment on-loan here at Benfica,” he told Sky Sports.
“I have very much enjoyed my time in Portugal but I have a lot of options open to me.
“There are clubs in the Premier League and La Liga expressing an interest in me but I will wait and see what happens at the end of the season.
“My main concern at the moment is to get fit again.”
