The 22-year-old former Tranmere and Bayern Munich player is looking for a new club after leaving Oakwell.
Jennings was declared a possible star of the future after shining at Tranmere Rovers following his Liverpool release as a teenager.
The winger scored 6 times in 26 league appearances in his breakthrough season at Prenton Park as he looking to be one that got away at Anfield, and it was enough to convince Bayern Munich to sign him up and enrol the Merseyside native into their academy system.
Jennings spent two seasons in Germany getting game time for Bayern's second string before heading back to the UK where he signed with Championship side Barnsley.
However, his time at Oakwell didn't go as planned either, starting with a red card on his debut, a loan spell down a division with MK Dons, and finishing with a relegation in his first season.

This season just gone was marginally better, as Jennings featured 19 times for the Tykes, scoring once and assisting four times to help Barnsley to an 11th place finish, though with another red card for the youngster.
The 22-year-old will now look to rebuild his career, with him being in danger of failing to capitalise on his undoubted potential.
