In Right side you see both a lack of width and a number of players standing still ball watching. This makes it very easy for the defence to hold the position close together making it harder for us to get through. In this position at least 1 player should be looking to make a run from the centre wide to try and create space.
In the Central video although there is a little movement you can still see a lack of urgency with players generally making the runs at a slow jog.
In the final video you can see how long it takes us to provide support to both the left back and left midfielder leaving them isolated.
All 3 videos are from the 1st half so should not relate to fitness
