AF CHANNEL: What is the most costly mistake an athlete ever made during a game?

Hello everyone! This is AF Channel. Here we offer you something to discuss, debate or games to play! 

Footballers are human as well as we are. Sometimes they make mistakes due to body health or nervous status. And sometimes they pay for that. They may cause their team to lose the game, and even ruin their own career. Today's question is: What is the most costly mistake an athlete ever made during a game?

Today, we invite one of the AFers, @jaineelbhatt, as the host of this topic. Congrats!

Here are some selected comments from AFers for the last topic: Where do you rank Pogba overall in the Premier League?

@Kemy: Pogba is in top form,I wonder why he is not getting the needed commendations, I remember last season around this same time Kevin De Bruyne was hailed by the English press as the best midfielder in the premier league, when that man city team was sweeping every team aside, today we aren't hearing anything about Paul Pogba from the English press, but let him score a goal and do his dance moves or post a picture of himself on Instagram it will be on their headlines,that's how they see him,I will tell Paul to focus on his football, and not think about any rating or whatsoever.

@Mc_donald123: To be frank with you all I have nothing much to say, just this adjective describes him all “Phenomenal”. Pogba has always had greatness in him, just that Mourinho didn’t make full use of Pog’s-magic. A few months back also he helped France conquer the world, and now helping Man United a long way. He is indeed one of the best and having someone like him, is a cheat to some clubs ?

@trivedi: Paul Pogba is the most versatile player I have ever seen.Dribbling,passing,defending,goal scoring.A complete player who can play anywhere in the field except goalkeeper.
