I think it is key that Sylla comes back in. You can have instances then when he and and Westwood sit, giving Delph a bit more licence to get forward, as the kid is doing it all on his own at the moment.
I am not sure whether we will see a change to the forward line to be honest, as at Arsenal and Chelsea, we looked very good attacking wise hitting them on the break. Bacuna might consider himself unlucky not to come in for Lowton.
