I would start the team that finished against City on Sunday, lets worry about players perhaps getting injured or tired when they are injured and tired. For the moment we are in a scramble and Spurs are showing some signs of cracking, if we can win tonight and Sunday then I think it will become too much for Spurs (who I expect to lose to City).
I dont see why we should worry about other teams, the only side we have left to play that are on a par with us is ManU. So why not just play our best team as often as possible these lads are fit so look after them between games and they will be fine.
