Playing five at the back is fine when you are up against two strikers or up against one of the league's shitey teams but I think the risk of doing this against The Rangers is that we will have three centre halves marking one striker and could get massively overrun in the middle of the park.
If you look at the last couple of league games, even though we have won them, Motherwell got in 12 attempts on goal, Hearts had 13. We have to be better than that on Saturday or we'll get beaten.
