Funny enough they were lucky to win the FA cup because i still see it as a something that was sentimental and rigged. Manchester City were in good position to win the game. They believed and was certain that they will win the EPL so that is the main reason they gave it out to Manchester United to as there City club to have at least one trophy in the season. All this things are understandable in football but no one talks about it because they see it as something that is not necessary to talk about.
Before the FA cup finals kicked off , pep guardiola while addressing the press sounded like they were having some kind of pity for Manchester united been a sister team and having to struggle all through the season with almost every of the league games they have been playing, I at some point felt he was sympathizing with them and so seeing Manchester united winning the FA cup at some point didn't come to me as a surprise because somehow I was hinted about it from guardiola's statements earlier before. It's not been spoken about because it appears most persons too were also sympathizing with Manchester united if not it was very obvious and clear Manchester city had more chances of winning the FA cup, even the squad that played the finals was their main first 11 so I believe Manchester city would be unstoppable on a normal day.
