Serbia's Viktor Troicki launched a vintage rant at Wimbledon on Thursday, blasting an umpire as an "idiot" and lambasting him for being "the worst in the world".

Fiery Troicki, the 25th seed, slumped to a 3-6, 6-3, 6-3, 2-6, 6-3 loss to Spain's Albert Ramos-Vinolas after slipping to match point down on a controversial ruling by umpire Damiano Torella.

A serve from the Spaniard had been called out but the decision was reversed, making it an ace.
