Any new manager should have the opportunity to rehabilitate all members of the squad. However I suggest he concentrates on passing, first lesson should be to pass to a team mate, second lesson should be to pass in front of said team mate and not behind. I note they have worked a little on throw ins, this is progress. If the passing lessons go well they should move on to finding a team mate in the box. Small steps.
Some of them should be taken aside to learn how to form a wall, which basically involves standing still.
Someone from the coaching staff should check with the sfa if it is actually mandatory to play the ball to the opposition full back when kicking off at the start of a half or after a goal.
