Yes, but we aren't privy to the ins and outs of player relationships / attitudes....work rates, effort in training etc. Following of instructions.
There's all sorts of factors that managers consider when deciding whether to play certain players.
I just trust that a good manager like Regis has his own reasons for not picking him and as it looks like he won't be here next year - it doesn't really bother me.
It could be that the manager considers other players as giving us a better chance of a result for whatever reason. It's not as if he's been a solid 9 or 10 every time he's played is it?
