You could call this the A47 derby - well, that is the route that most of the Leicester fans will be taking on Saturday anyway.
There will be a sell-out crowd at the ABAX Stadium and I think they are in for a decent game, because Peterborough are useful going forward.
Leicester needed a replay to get past another League One side, Fleetwood, in round three.
They were not at their strongest but they picked a team that got them through and I think Claude Puel will do the same here.
Leicester do not have any relegation worries and this is their only chance of winning something this season - I just hope they have a proper go at it.
