In the second set after the decisive break of Tsitsipas, Medvedev yelled at the chief referee. «To be honest, I don't think such negative emotions help me, I often lost because I lost concentration. After I yelled at the referee, I I thought: «This is wrong.» I again caught the concentration at the beginning of the third set, served well, these feeds returned me to the match. I lost a little energy, but managed to return. I'm happy that it worked, «Medvedev said on the air of the Eurosport TV channel.
