Richard Grenell thundered: We cheapen ourselves if we don't allow Novak to play the US Open!

The former special presidential envoy to the Kosovo-Serbia dialogue, Richard Grenell, asked the US authorities to allow the best Serbian tennis player, Novak Djoković, to play at the US Open.

- Let @DjokerNole play in the @usopen! The U.S. Open cheapens itself when it bans one of the best players in the world - Grenell wrote on his Twitter account.

According to the regulations currently in force in the USA, unvaccinated citizens of other countries cannot travel to America.

The US Open will be held from 29 August to 11 September.
