Kaz is certainly an option if we are really going to go for it but I'd worry that his defensive play isn't as good as Barnes.
Whatever, it is a great position for Gus to be in as any one of Hammond, Barnes or Kaz is a good option. He may even spring Vicente from the off, but that may be a bit too cavalier given the importance of the game?
I may be wrong, but I'd have thought Gus would want Vicente on in extra time against a tired Palace, and for the shootout if necessary, and I doubt he could last 120 mins. Would be astounded if the dagger started.
