May I offer a couple of suggestions, Ryan Williams is a very good winger, however he is wasted in this "number 10' role, please play him where it suits everyone.
Secondly, is Zak Vyner really up to the job ?
I know that young Josh looked poor at first last season but he did improve rapidly, sadly young Zak doesn't seem to be.
If Jones is fit get him in for a bit.
Best wishes TLC.
