You said a manager is only as good as his players are.
I am saying a player is only as good as his manager is.
First one: Leicester when they won the league. Huddersfield beating United. Just examples.
Second one: Arsenal and Wenger. Perennial underachievers for the last 8 seasons or so. The odd FA cup aside we have been scraping fourth and consistently been trounced and knocked out in the R16.
So our players are only as good as our manager is: hence we are playing like a 5-6th place team and not as title contenders.
