Football played with Math strategy !
World No.1 (Germany) Lost to World No.59 (Korea) – why ?
Reason: Math !
For weak Korea to win, the best strategy is to keep the goals number as low as possible with strongest defence.
Note : 2017 International Math Olympiad (IMO) World Champion Team was Korea.
The actual Game proved the Korean “Math” strategy was right: (2:0)
