Former World No. 4 Nicolas Kiefer has criticised the players who attended the Adria Tour, saying that they should have been better informed and advised not to play in an event without the required safety & social distancing norms.
According to L'Equipe, the German says, “Zverev and Thiem are well advised. Why did nobody tell them in advance: "It's a nice invitation, but you won't go? You really have to wonder if they have anything in mind other than tennis.
You can take the lead and wonder what a Zverev, a Thiem and many other players thought during such an event. Viktor Troicki even came with his pregnant wife. With a little common sense, you wouldn't have done it! Each player must be mature enough and experienced enough to assess the situation more critically.
This will have serious consequences. The French Open was being planned to be played in front of spectators. Will the risk not be too high after these events?"
