Sanson and Luiz with Marv for me.Can help with transition from defence to attack instead of lobs/hoofs.Can both run with the ball which has been missing since Jack left.
I do realise this won't happen.
He came on after about 30 minutes as Bielsa subbed their DM who'd clattered Jack about 3 times and got booked.Was seen as a brave move to sub someone so early.Actually changed the game to be fair.
