My two cents on Sykes would be that he's always been that cliche of a square peg in a round hole for us. He doesn't quite have the physicality to play in CM (I appreciate he had some excellent games in the run-in, but against the very best sides in this division he was overrun), and he doesn't have the end product or pace to play as an out-and-out winger. He's a natural 10, which we don't play with.
I really like Sykes, I like his tenacity and cheekiness on the ball (how many other players we've had in recent history try pirouettes and dragbacks to the same extent he does?). But while he's a useful depth player, and can be a match-winner against the middling-to-poor teams in this league, I don't think we play in a way that really suits him. 300k for a rotation player is a no brainer for me.
Plus, as someone said above, I'd love to see LCP given more chances as the rotation player in CM in the coming season. I think he's going to be absolutely quality.
