Flood failure sets up Old Firm final
Flood, who is expected to sign for Celtic, missed his second penalty of the sudden-death shoot-out as the Hoops won 11-10, to set up an Old Firm final.
Both sides had enjoyed strong spells in the goalless 120 minutes with Flood twice coming close and Georgios Samaras and Marc Crosas both hitting the United bar late in extra-time.
