Players of that age cannot sustain the intensity required in a Klopp team.
The players currently playing cannot go 90 mins without having several brain farts.
It would be difficult for the younger players on the bench to come on and perform well. Witnessing the calibre of play in front of them week after week would not inspire them, merely lull them into a sense of apathy. How must Grujic feel watching Henderson
chasing seagulls on the beach, week after week? He would be thinking why did I come here when this is the standard required?
