It's kinda of a weird throwback tbf that this tournament still has two legged semi finals. I think it also used to have a two legged final and two legs in the early rounds, and I also seem to recall it was single leg semis during covid, but it is still a little bit of a curious outlier.
Sadly I suspect it'll be Liverpool triumphing in the other semis given Spurs' lack of defence. Their concession of 6 goals against Liverpool the last time they met just a month or so ago isn't the greatest guide that they'll be more resolute in the meeting tonight.
Given Young's tantrum last 2 days before his U-turn, my guess is that the Eavis' first plan was to try and persuade him to change his mind. A project that succeeded, clearly.
