The goalkeeper in football is a person on the field who protects their team's goal from balls that opponents try to score. Simply put, it's someone who catches or deflects balls to prevent them from entering the net. The Ukrainian equivalent for the word "goalkeeper" is "воротар". So if you hear "воротар", know that it's the same football player, but in the language of our country.
When we talk about who a goalkeeper is in football, we mean a key role in the game, as they are the last barrier before the opposing team can score a goal. So what is a goalkeeper? In English, this word means "one who keeps the goal". As you can see, their task is literally to "keep" the goal safe.
If we recall a real example, we can mention Andriy Pyatov, a famous Ukrainian goalkeeper. He defended the goal of the national team of Ukraine for many years and proved himself to be a true master of his craft. He caught and deflected balls from the strongest attackers, repeatedly saving his team from conceded goals.
