The winners of tonights match (ko 7:45pm) will face an away trip to either Orient or Margate. They also replay tonight. Should it be Margate they are currently playing at the Crabble, home of Dover FC so the combination of a trip to Calais on a Christmas booze cruise as well as the football is an option. If we get knocked out by Tranmere then it's Tesco Extra on Western Avenue.
Lennie will probably make around 5 or 6 changes, more team news will appear later. Players hoping to come in inc Leo, Campbell, Bonner as well as the three named above.
Lennie of course must field a full strength team at Loftus Rd in a crucial Division 2 battle on Friday night.
Tranmere come to Ninian Park for the second time this season. Their first visit a few weeks ago ended in tears as City won 4 - 0 in front of the Sky cameras. Tranmere will be without on-loan Adam Proudlock who is cup-tied but will look to Stuart Barlow and former City striker Simon Haworth as their attacking force. Don't forget both players scored in the game at Prenton Park 10 days ago.
A lower crowd is expected than for a league game as normal league admission prices apply. A chance missed maybe to offer a special price for the game?
There will be coverage of the game on Radio Wales and there will be plenty of discussion in the chat room on this site.
