I'd be extremely happy with a 1-0 win; no matter that their league position is under threat, Birmingham will still be fired up for this QF tie. I'm a bit concerned that Rafa may still play the bumbling Traore due to him being forced to schuffle his pact with the very busy game schedule.
I really hope that they become more focussed on surviving for the EPL next season, and would not give much emphasis on this tie.
