The concept of supporting clubs is weird.
My son has no favourite team apart from our local team.
He supports players.
His favourite players are Kevin De Bruyne and Courtois. When City plays Chelsea, he hopes both play a good match and that he seems a good match.
A question.
You are a Slovakian Liverpool fan, Pipa (or others).
You have a son who is exceptionally good at football.
He can play for Manchester United. How do you react?
I would love him to be best he can be of course at anything he does, except murdering people

just kidding... i wouldn´t stop supporting the club i grew up supporting, but at the time my son would play for United, i would wish him only the best obviously.
But i repeat, maybe when i was younger i supported football more as a passion type of fan, but now i look more in to the sport, the game itself, what coaches have to do etc... i look on the educational part of the game, how it is to improve already skillful players and make them better..i look more in to tactics than before
But don´t get me wrong, i think at the same time that rivalry´s are very important in sport, for the fans there is nothing better than beating their main rivals etc... at any sport... i know that feeling as a hockey supporter of my second tier local club here in SVK. I follow them during playoff on all away matches and the moments we as fans experienced will stay with me forever...
So all in all fans are why footblall is popular around the world, they are the reason n.1... the game is simple, but without fans the game would be nothing... without having urge to beat someone, what would be the point? i mean the game should be ballanced, there shoudl be rivalry, but not hate....more like respect to your oponent... i respect United as a club, i don´t hate their fans etc..but knowing hisotrically what it means to LFC supporters if the club beat them, i feel happy if they do, more than anyone...except Everton as well..but Untied are the ultimate club to beat for LFC and it won´t change for long time..
