Just been looking at the table, thinking about what results we want to see today. The conclusion is that we want draws in all games! We are in a strange position of needing to stay in touch with teams at the bottom AND near the top!
4-5-1 is only 4-5-1 when you dont have the ball. It should naturally become 4-3-3 when attacking.
If you play a rigid 4-4-2 then the full backs have to cover alot of ground. 4-5-1 to 4-3-3means they dont have to and the wide players can support the striker.
Murty returning might also change things.
