Rudy Gestede is open to new offers after leaving Middlesbrough.
The 31-year-old has left Riverside Stadium after his contract expired.
A former Aston Villa and Blackburn Rovers player, Gestede said: "I'm open to a new challenge.
"At my age, we need to talk about the conditions and the way they want to play, as it's not like I've got 10 years in front of me.
"I need to pick the right challenge for me and my family, but especially for me and my football, as I know my family will follow me everywhere, so it's fine.
"It could be in England, it could be somewhere else, I don't close any doors, I just need to find the right one for me."
