Arthur Zanetti gave a taster of the carnival atmosphere the world can expect at the 2016 Rio Games when he sparked wild celebrations on Monday by becoming the first Brazilian to win an Olympic gymnastics title with victory in the rings final. So unexpected was his win over favourite and 2008 champion Chen Yibing, most fans at the North Greenwich Arena did not even note Zanetti's shock triumph until there was suddenly a loud commotion from a small bunch kitted out in green and yellow.
The 22-year-old gymnast rushed towards his supporters the moment his score of 15.900 flashed up and, had the stands been a little lower, it looked like he would have dived into the crowd. Instead, he snatched the Brazilian flag thrown his way and ran off on a victory lap having usurped Chen by 0.1 of a point. Italy's Matteo Morandi won the bronze.
