Like some have said already, I can't see the cup being a priority for Norwich...the riches on offer for staying in the premier league far outweigh a run in a cup they're never going to win anyway!....so I can see them fielding a weakened team for this. As for us, I think it's important to stay in all competitions for as long as possible and despite the injury's we've suffered this season we should still have enough to win this and rest a few aswell. With that in mind I would go for.......
Defence,
Willie, zab, otamendi, demichelis, Clichy.......zab and Clichy need game time and with company and mangala injured we have no other options at centre-back. (On the plus side, four of those five speak the same language so communication shouldn't be a problem)!
Midfield,
Fernando, fernandinho, delph.....let Fernando and delph protect the back four and allow fernandinho to support the forwards whenever possible.
Forwards,
Navas, kelechi, sterling.....those three should cause a lot of problems to a weakened Norwich defence with their pace, enthusiasm and unpredictability!
With that team I'd go for à 3-1 win!
