Wataru and Gravenberch will probably be rotated for that no.6 role. Most games where we are expected to have longer bouts of possession then I expect to see Gravenberch who will offer more with the ball at his feet than Endo does. I expect to see Wataru starting the games where it's expected we'll have more defensive work to do.
In addition to that, I think that Endo will be brought on to close out most of our games even when Gravenberch starts.
We'll have to give them both time to adapt. Alexis and Dom have hit the ground running, but this is more of an exception than it is the rule. Our new midfielders usually take time to adapt and I think it will be the case with Wataru and Ryan.
