Yes, sir.
For a coach to need to tell a full-back to aggressively sprint into an overlap position to create an overload, is quite frankly shocking to say the least. If it's obvious to a fan watching his team, then it ought be all the more obvious for a professional at the top of the game. When I see Alba almost as high as Suarez wide on the left, I think 'he understands', and when Robertson bombs down the left in anticipation for the switch from Salah to Wijnaldum to Mane, I think 'he understands'.
But when I see Shaw/Young 20 yards behind Martial, waiting either for Martial to pass the ball backwards, or take on two players double-teaming him on his own, then I think 'they don't understand'.
