After last years' abysmal show from the EFL Championship Team of the Season (it had 12 bloody players in it), it shouldn't surprise me that Tom Cairney isn't in. Best midfielder in the division, more assists than Knockaert, more goals and assists than Mooy and Shelvey, more passes than Mooy and Shelvey, better passing accuracy than Mooy and Shelvey and more chances created than Mooy and Shelvey. In no way can you convince me than either player deserves in ahead of Cairney.
As for Malone, it actually doesn't surprise me he's in it because when you actually look at creating your own Team of the Season, it's pretty void for left backs and Malone has been the best of the decent ones. He's done well and I think I'd struggle to pick another divisional left back that would be an upgrade (at least on the seasons form).
The worst thing about Cairney not being the Team of the Season is that it probably foreshadows him not really being in the running for Player of the Season... I don't think he's even been nominated for Player of the Month, let alone winning it. Oh well... I'm sure he'll still bring up a lot of interest this summer, even if the "experts" don't think he's good enough for that team.
