For me the main problem at the moment is when we don't have the ball.
Our press is not man for man and Stoke and Bristol especially always seemed to have a spare man they seem to find with a couple of passes around our front 3 and our midfield and defence then set up in their defensive positions allowing the opposition normally a free run into our half or final 3rd.
All this is meaning we are not winning the ball back high enough up the pitch which then means we have to pass it around the back for ages looking for any glimpse of space through a packed midfield/defence rather than having any opposition players out of their defensive positions if we won the ball back higher up and broke away.
