You clearly have little to no understanding of football do you Dave. By starting Young, who has been a liability defensively you are forcing Harrison to spend most of his time and energy backing up Young, that coupled with the fact that Young struggles to get up and down the pitch means that Evertons right hand side is useless in anything other than sitting in and defending. This also affects other areas of the team, the team as a whole ends up sitting deeper and deeper, and as a consequence finds it harder and harder to get out of its own half.
But I wouldn’t expect you to understand that Dave, you don’t actually watch football for the game itself do you.
