The system as you put it is a starting point, the main thing you need is players with football intelligence who can look for a free player and make a pass to suit the situation.
Last night was pathetic, our only plan of attack seemed to be kick it to Garnacho because he's fast.
At dead balls Onana kicked it to the nearest full back who then passed to a center back who then passed it back to Onana to hoof up the field to the opposition midfield/defence.
We even had two throw ins level with the oppo penalty box that in 3 passes ended up with.........you guessed it Onana.
We can and have played much better than that but for some reason last night they were terrefied and lacked any pride/intelligence at all in order to stay safe.
