I'm not so sure that Jack is the cesc/ozil type of ball player anyway.

What he has, is balance, touch and hustle. He gets stuck in, brings the ball away, drives forward, sets the tempo and pings passes out. Whilst he can spot a pass, he's the engine in the midfield, as opposed to Ozil, who would be your no.10, creating the chances and being artistic.

Both Rmasey and Wilshire are reasonably similar, and that is why I think the pair will eventually be the "double pivot" behind Ozil.
