Now it is said by The Scottish Sun that Hirst is ready to make the switch for next season and beyond.
Speaking about youth international experience with England previously, Hirst said: “When I was playing for the England youth team I was playing with and against some of the best players in the world.
“I was at Sheffield Wednesday at the time and I was meeting up with lads who were at Arsenal, Chelsea, Manchester City and other top Premier League sides.
“Although it was a bit different for me, it was still a great experience to see different countries, different stadiums and different styles of football. It keeps you switched on and it was better than just having a rest from your club time.”
