Scott Brown urged the Celtic board to keep Hayes at the Scottish Champions for at least another season and help them reach ten in a row.
Celtic had confirmed that Hayes will no longer be a Hoops player on Saturday afternoon.
The Celtic captain wanted Lennon to retain Hayes not just for his work ethic but his experience and presence behind the scenes.
This Hoops squad is still a younger squad and Brown knows how much Hayes brings to the younger members of the team as his professionalism rubs off. (source)
With Fraser Forster set to return to Southampton, as things stand, it’s easy to see why Brown may have wanted to keep Hayes around as he was one of the few experienced players in the Celtic squad.
