Slovak player's command of Polish helped his team to decode Poland's tactics

Haraslin was able to understand Poland's game plan after learning some Polish during his five-year stint with Lechia Gdansk.

When Plan A did not work for Poland, their players tried to switch to Plan B by passing instructions in another language. Unfortunately for them, Haraslin foiled those plans as well.

"There was a situation where (Polish defender) Kamil Glik was telling (team mate Grzegorz) Krychowiak where he was going to run," Haraslin told the daily paper SME.

"I immediately warned my team mate Tomas Hubocan to be wary (of the move). When Glik heard me, he switched to French. But I understood that too, because it is similar to Italian.

"I told him 'Kamil, I understand you anyway'. So he left it," added Haraslin, who joined Serie A side Sassuolo last year.

Slovakia, who surprised a Robert Lewandowski-led Poland team 2-1, will face Sweden in their next match on Friday.
