Can Rangers cope __with Celtic's pace and power?
Rangers have a big problem. We know they haven't got a manager in place and Celtic have been running the show for the whole season __with pace, power and movement.
Rangers haven't got an ounce of pace at the back. They have to change their formation and sit a little bit deeper. They sat deep with four at the back the last time they went to Celtic Park and they couldn't get out, so they need to change their prospects by going to a back five.
When there's pace in behind they are suddenly exposed. They can't contain anybody with pace and Celtic have got an abundance of it. What's going on at the moment doesn't work so you have to change it.
With the change in formation they would protect themselves and it can give them an advantage because the back five allows Lee Wallace and James Tavernier to get forward.
Wide men key for Rangers
With five at the back you can get Wallace and Tavernier high up the pitch. That's where they can have an influence because they are better with the ball.
The two strikers in this system need to keep Celtic's defence occupied but it's the wing-backs that are key, especially in advanced situations.
If they go with a back four it's damage limitation. It's nothing else but damage limitation because it will only be a matter of time before Celtic's pace and power rip them apart.
If they go with a back three, sit in and be cautious they have the legs to get forward and cause Celtic problems. Rodgers' side are strong favourites but this plan can give Rangers a stronger foothold in the game.
How do you shackle Dembele and Sinclair?
Moussa Dembele, who has scored 17 goals in the league, is playing out of his skin at the moment but Scott Sinclair is the key to the game.
Rangers have to try and show him into traffic because he's so dangerous when he cuts in off the left flank. When he does that then you see Dembele popping up wide on the left.
They are not really a partnership but it works a treat for Celtic because of the pace and power.
If Rangers play with a back four then ball over the top is on all day for Dembele and it could prove to be a very difficult afternoon for the visitors.
