You can see Allen shout but he probably doesn't know the "man on" shout yet. Like he might know the words but he might not have ingrained in his instinct yet to take action now if that makes sense. If I hear the words "man on" I don't process it so much as my instinct takes over to act.
Anyway, aside from that, I like the look of him. Especially going forward. Quick, composed, neat and tidy and a bit of adventure about him. Didn't once see him do Enrique's 'dribble into a dead-end' special move.
