Following his loss, a video emerged online in which the 26-year-old is seen engaging in a war of words with a fan at the venue.As Medvedev was leaving the stadium, a person can be heard calling him a "loser." He immediately turned and walked up to the fan to confront him. After a few seconds of heated arguments, Medvedev walked away. Reacting to the video, Kyrgios called for respect towards the players from fans."Disgusting behaviour. This is the best we have in the sport, fans need to show some respect," Kyrgios tweeted.Nicholas Kyrgios@NickKyrgiosDisgusting behaviour ☹️ This is the best we have in the sport, fans need to show some respect. twitter.com/dmedvedevfans/…Meddy Family@dmedvedevfansGod, how awful can fans be when they chant ‘loser’ to a tennis player after a tough battle on the court 🏻Achieve something yourself in this life..Having respect for another person is an important rule of a human being.12223623God, how awful can fans be when they chant ‘loser’ to a tennis player after a tough battle on the court 👎🏻Achieve something yourself in this life..Having respect for another person is an important rule of a human being. https://t.co/raFBQ8AXN7Disgusting behaviour ☹️ This is the best we have in the sport, fans need to show some respect. twitter.com/dmedvedevfans/…However, his tweet didn't go down well with most of the followers and they let him know why.
