hahahaha ok

also what mick forgot to mention is the away goals rule which can be slightly complex

now liverpool are 2-1 up

they have two away goals but the second leg is at anfield so any goals barca get will be away goals

if the scores are level after both legs the team with more away goals goes through

for example if barca win 1-0 they are still out as the score would be 2-2 overall but liverpool would have 2 away goals to barcas one

if barca win 2-0 they would be through
but if it ends 2-1 barca then its extra time and penaltys
