Djokovic defeated Cameron Norrie 6-4 6-4 to secure a 2-0 victory for Serbia over Great Britain in the quarter-finals but was very unhappy when a section of the 5000-strong British support tried to drown out his post-match interview with drumming.

Djokovic, who had earlier ironically blown kisses to a vocal British fan at the end of the first set, told the supporters: “Learn how to respect players, learn how to behave yourself.” He then added: “No, you shut up, you be quiet,” as the row continued.

British captain Leon Smith played down the incident, arguing that noisy, partisan atmospheres are central to the Davis Cup.

An LTA spokesperson said: “Passion is a unique component of the Davis Cup and it is a competition where emotions run high. We are lucky to have strong travelling support and would always encourage GB supporters to behave with respect for our opposition.”

Rather awkwardly for the governing body, it does provide help to some supporter groups, including the one in question, the Stirling University Barmy Army, to travel to ties in order to create a good atmosphere.

The row overshadowed what was a disappointing end to an encouraging season in the competition for Smith’s men.

Norrie played well and kept the scoreline relatively close against the world number one without ever remotely threatening an upset but the damage was done when Jack Draper lost out 7-6 (7-2) 7-6 (8-6) to Miomir Kecmanovic in the opening rubber.
