For info, and a bit of a warning:
Southampton have taken roughly the same amount of tickets as Leeds did. Spurs took less.
So in theory, everyone who has both games should get one.
However, as I've alluded to above, tickets for semi final second legs have a much higher demand, and no doubt far more sponsors, corporates, ex-players, and 'celebrity' Reds will be looking for tickets for this one, when they weren't necessarily looking in the fourth round. And LFC being LFC, will no doubt prioritise some of those demands above those of the people who actually bothered going to the earlier rounds. So I wouldn't be taking anything for granted.
