Leo for me, with Bragg as most improved/young player.
However, I feel that most of the team deserve it, and wouldn't really be surprised if anyone did.
Tonda has pretty much improved every player. It also doesn't seem like players are getting annoyed if they are not in the starting 11, as he is rotating the squad really well.
Also, although I have no evidence, I do think certain players that left, were bad eggs and toxic. By then departing, the team could only then kick on and turn it around.
New signings and returnees have fitted straight into the squad.
