I know this resurrects the Arnold to midfield discussion but if this lad turns out to be as promising as he appears to be then that right had side has the potential to be lethal, Ramsay, Arnold, Salah and Elliot (albeit Elliot is looking good moving slightly inside).
He actually looks like another player who can provide a threat, let's put them both in and they can share the work and keep the other team guessing, other teams do it with great effect.
