And having spent a season on loan with Torino, Hart says he might need to head abroad once again to recapture some form.
He told The Guardian: "I enjoyed being part of that club. In terms of being in a different country, experiencing a different culture, playing a different league, I absolutely loved it. It's definitely something I'd love to do again."
When asked if clubs still wanted to sign him, he said: "I believe there will be. But they all need to work out exactly what the hell's going on. I like to think I'm a good catch. I'm on a free contract, I've got experience and real hunger. The Premier League has been great for me but I'm more than willing to spread my wings."
Then quizzed if he would move to Italy, Spain or Germany, he said: "I'm totally open. I just want to play at the highest level I can. In England, I don't feel I am going to be able to do that. Maybe if I hadn't achieved what I've done in this league I might not be so ready to step away. Don't get me wrong. I'd love to have another big chance in England, but it could be difficult."
