I've just seen a translation from a Ukranian speaker on reddit, and Zinchenko himself doesn't say anything bad at all and the bit when she has a go at Pep is filmed immediately after the game in Lisbon when we've just lost.
First he said everyone is very good a this level and these matches are determined by who has more determination that day and Lyon fought harder.
Afterwards he just explained why he thinks they couldn't get control, because they were missing a player up front because they had 3cb+2dm who weren't participating in the game most of the time.
Then he said Pep didn't enter the dressing room after the game and there isn't anything to say anyway after such an event. And that he feels really bad for players who are leaving like Bravo and Silva and that they deserved a trophy.
31 pages of drama and bullshit over absolutely fuck all, just a wife getting a bit upset and saying what half the fans on here said.
