For any confused souls out there Should Chelsea win tonight's game 2-0, then the tie will go to extra-time. If there are no further goals, it's penalties. If Chelsea win 3-1, we have extra-time and if there are no further goals,Swansea win on away goals. If Chelsea win 4-2, we have extra-time and if there are no further goals we go to penalties. If Chelsea win 5-3, we have extra-time and if there are not further goals,Chelsea win on away goals. If there any more goals than that in the 90 minutes then we'll all just enjoy it...
