Apparently Röhl's number 2, go to, lackey, was Sacha Lense. No idea where he is now but he's more likely to go after him.
I don't think Lense was a coach as such, but according to Lee Gregory, Röhl didn't say anything to the players without Lense being present, and in fact he sometimes left the dirty work of telling players they were in/out of the team to Lense.
I'm pretty confident he won't be after Pederson.
