Argentina's heroic goalkeeper Sergio Romero, appeared to closely look at detailed notes before ultimately saving two of Hollands spot-kicks and sending his country into their first World Cup final for 24 years.
According to the Daily Mail, Romero's brilliant penalty saves from Dutch duo, Ron Vlaar and Wesley Sneijder, as the South Americans side won 4-2 in a dramatic shoot-out, was all down to his research, after the lacklustre match ended in a stalemate.
There is no doubt that losing any important game on penalties is the worst way to go, let alone a World Cup semi-final with heightened belief, that who ever progresses is down to blind luck.
However, in São Paulo last night, Argentine stopper Romero proved that you make your own luck as he was seen looking at notes he had made before every one of Holland's penalties.
The Sampdoria man had prepared himself for his side's semi-final to go all the way to the wire, by writing up notes of where the dutch players were most likely to place their penalties, which he evidently needed.
The 27-year-old kept his notes hidden down his shorts and sneakily refreshed his memory before setting himself to face each crucial spot-kick.
Netherlands boss Louis van Gaal- who is famously known for taking notes himself - will be the most frustrated of all, as he once coached Romero when he was in charge of Dutch side AZ Alkmaar.
The newly appointed Manchester United manager expressed that a lot of it was down to luck, but also revealed his severe annoyance that he didn't see what was coming, as he taught the Argentinian everything he knows.
'We didn't lose against them, but the penalties are down to luck,' Van Gaal told reporters.
'I taught Romero how to stop penalties, so that hurts.'
Van Gaal also admitted, how his side were already overcome with nerves before the shoot-out began, as two Dutch players refused to take the first penalty, which Romero eventually saved from Aston Villa defender Ron Vlaar.
This incident, however, is not the first to happen at a World Cup. Former Germany and Arsenal goalkeeper Jens Lehmann also stated, that he too studied notes before his side's penalties against Argentina in the 2006 World Cup quarter-final in Berlin.
The Germans won that shoot-out with charismatic keeper Lehmann saving two but diving the right way for all four penalties. Not long after, his historic notes sold at a charity auction for a staggering £1.3 million.
