It's not defenders making mistakes that loses us games, all defenders will. It's cutting inside and putting the ball in the stand, it's missing penalties, it's balls played behind a runner, crosses not beating first man, the list goes on and on. The players are doing what they should, they just don't have the quality to do it well
Their goal is the perfect example, what did cannon do in that first half other than score a brilliant finish? what did andre gray do last night other than score 2 worldies? We don't have one of them
