Rio Olympics 2016 football: Defending champions Mexico and crisis-hit Argentina both crash out at group stage

LONDON 2012 gold medallists Mexico crashed out of Rio 2016 at the group stage and so did crisis-hit Argentina.

In truth, Mexico were the better side against South Korea but couldn't find a way through.

That allowed K League Classic star Kwon Chang-Hoon to strike in the 77th minute for a 1-0 win.

He found an easy passage through Mexico's practically non-existent back line and netted what was his country's first shot on target.

A Lionel Messi-less Argentina needed to win against Honduras to advance to the quarter-finals but could manage only a 1-1 draw.

The Central Americans went ahead through Antony Lorenzo's penalty 15 minutes in.

Argentina's Mauricio Martinez equalised in stoppage time but there wasn't enough left on the clock for a winner.

Freiburg striker Nils Petersen scored five times and Arsenal's Serge Gnabry bagged a brace as world champions Germany smashed Pacific islanders Fiji 10-0 to seal their place in the last eight.

Portugal secured top spot in Group D with a 1-1 draw against Algeria in Belo Horizonte.

Japan beat Sweden 1-0 courtesy of Shinya Yajima's 65th-minute strike while Colombia saw off Nigeria 2-0 thanks to goals from Teofilo Gutierrez and Dorlan Pabon.

Hosts Brazil face Denmark needing a win to advance from the group stage and it's likewise for South Africa, who take on Iraq.
