It's been a long time since Alexander Zverev was accused of his ex-gf of assault and the ATP is yet to reach a conclusion on their investigation.
Some journalists pointed out some interesting facts surrounding that showcasing just how badly the ATP really handled it. It's taken them a long time to even start their investigation and since then it's been 458 days of 'investigation'. They managed to stage a whole Netflix show that is produced and will air shortly in a shorter time span than this investigation is taking on.
It's not a complicated case and the evidence is quite compelling so it's baffling why the ATP takes so much time. When you look at the original accusation and how old they are, you find it very hard to explain why it's taking so long.
