Meh, pussy. He actually cried at half-time while Argentina were still 2-1 up, "Have you seen that? There must be 100,000 people out there. If we win they will kill us". He didn't want to go back for the second half.
Previous Olympics finals had 24,000-28,000 spectators. With 100,00 (10-20,000 of them Argies) FIFA was concerned, had passed on their concerns and the Uruguayan players had been specifically instructed not to tackle hard or trigger any sort of crowd reaction (despite there being fences and a huge moat around the pitch).
As Monti cried his eyes off, the Uruguayan changing room was visited by FIFA authorities congratulating the players on their behaviour (my grandad actually was there and had to show agreement except that he was fuming!). The moment they left, Monti's equivalent for Uruguay (Lorenzo Fernandez) told the players he didn't care, if they lost he would kill them all. Nassazi added: "He will kill you, and I will bury you. Now, we'd better start getting stuck in or we are not winning this".
Monti did come back for the second half but was non-existent (in the video I posted, third Uruguayan goal, he is the one doing monkey jumps in no man's land, not quite closing down Andrade, nor close enough to any o
ther attacker). Years later he would confess: "I realised if I touched anyone all hell would break loose. I was a marked man, so I told my half-back partners: "You get stuck in, because I can't". What did they want? For me to be a football hero?".
In 1934 it was all a lot easier, playing home, and this time there was an actual death threat. If they lost, straight from Mussolini's mouth, "firing squad". You Argie? I don't care, you eyetie today, you win or me kill. Great motivational speech
