Yes, we can't speculate just because of the rumors circulating because in fact there is no recent news regarding evidence that Man City really made this dirty mistake. If that really happens, Man City is threatened with being expelled from the EPL, which is quite a severe punishment for Any team that tries to violate must therefore be careful if they want to make dirty transactions. I hope the Man City rumors don't come true because it would be very sad to see Man City not be in the EPL if that really happened.
Manchester City is currently the best team in the English Premier League and seeing their removal wouldn't bring any good news to the ears, rather it will saddens and wrapped up the consistent outstanding performance of elite teams. We know how these teams run their operations, they ensured they're not violating any rules and if there's need, they make sure to cover their tracks. I'm just hoping this piece of information to be rumour because there's no evidence of the dirty work been carried out, though investigations are still ongoing.
