Something absurd is going on in the Italian Federation: Zaytsev may be sent home because he is using Adidas shoes (his personal sponsor) instead of Mizuno shoes (NT sponsor). And wants to keep using, as far as I understand from the news in Gazzetta.
He is a drama queen, that's why I don't like him.
He seems to life to be sponsored: just look at his instragram
If there's a rule, you have to respect it.
Next time he should think twice before signing something.
