Olympic viewers thrilled as remote control bus delivers match-ball before rugby sevens kicks off

Spectators were left baffled in the opening fixture when the match ball was delivered onto the field in the nippy vehicle.

Team GB captain Tom Mitchell scored one of the side's six tries in a convincing 34-0 win against hosts Japan.

Great Britain beat Canada earlier and now top pool B so their chances of reaching the quarter-finals look good.

The knockout stages begin at 09:30 BST on Tuesday.

We’ve picked our ultimate Team GB Sevens team that would definitely win gold at the 2021 Olympic games in Japan.

Stuart Hogg (Scotland): He is the Scotland captain and the man that makes them tick. When he’s not in the field, the Scots struggle to mix it with the big teams. Playmaker, motivator, kicker – he’d be our captain on this stage.

Louis Rees-Zammit (Wales): He burst on to the international scene a in 2020 and hasn't looked back. His blend of composure and speed would be perfect for the sevens game.

Jonny May (England): A prolific and pacey finisher, he has reached 29 Test tries. Despite his club ’s poor results, May also scored a total of 30 for Leicester over just 44 matches in Premiership and European competition.

Finn Russell (Scotland): His undoubted talents would find a natural home in the shortened form of the game. His passing ability and knack of manipulating space and defenders would be prizes assets.

Jamie Ritchie (Scotland): The Scot would be the beast up front. A tackling machine, with massive go-forward and ferocious clear-outs at the ruck – Jamie would give GB a hard edge that all good teams need.

Maro Itoje (England): Every sevens team needs a kick-off and lineout specialist may be required. No one fits that bill better than England’s sensational Itoje. His aerial ability and all-round athleticism is up there with the best. Tackles, turnovers, off-loads and bags of enthusiasm – Itoje would bring a medal-winning game to a Team GB Sevens team.

Justin Tipuric: The Wales flanker has an all-round game well suited to Sevens. Turnovers at breakdown, high work rate and great handling skills all add up to a big impact for Team GB.
