GROUP A
Team GB 3-1 United
Barclays Premier League legend Ryan Giggs opened the scoring as Stuart Pearce's Great Britain side earned their first win at the Olympic football tournament at Wembley Stadium.
The Manchester United veteran headed the home side in front from Craig Bellamy's cross in the first half.
A lively UAE side drew level with Rashed Eisa's cool finish after the break.
But Swansea City's Scott Sinclair restored the lead moments after coming off the bench before Chelsea's Daniel Sturridge put the gloss on the scoreline with a delightful chipped finish following Bellamy's incisive pass.
Senegal 2-0 Uruguay
Moussa Konate was the star as 10-man Senegal earned a surprise victory over Uruguay.
The Maccabi Tel Aviv striker touched in from close range to put Senegal ahead before Abdoulaye Ba was sent off for a foul on Liverpool's Luis Suarez.
But Konate struck again with a header, meaning the South American side will almost certainly need to beat GB in the final group match on Wednesday to qualify.
GROUP B
Mexico 2-0 Gabon
South Korea 2-1 Switzerland
Tottenham Hotspur's Giovani Dos Santos scored both goals for Mexico as they beat Gabon to move to the top of Group B.
Dos Santos, on as a second-half substitute, curled in the opener on 63 minutes, then hit an injury-time penalty to complete victory.
Arsenal's Chu-Young Park scored the opening goal as South Korea beat Switzerland to give themselves an excellent chance of reaching the last eight.
Park's header was soon cancelled out by Innocent Emeghara's effort, but Bo-Kyung Kim netted with a volley to seal victory.
GROUP C
Brazil 3-1 Belarus
Egypt 1-1 New Zealand
Chelsea's Oscar opened his account at the Olympic Games with the third goal as Brazil came from behind to secure a victory which ensured their progress in the tournament.
Renan Bardini headed Belarus into a shock early lead, before Alexandre Pato fired in an equaliser.
Neymar put Brazil ahead with a superb free-kick on 65 minutes before Oscar struck after good work from Neymar to complete the win.
In the other Group C match, West Bromwich Albion's Chris Wood scored from close range to put New Zealand ahead, but Egypt hit back through Mohamed Salah for a draw which leaves both sides struggling to qualify for the knockout stages.
GROUP D
Spain 0-1 Honduras
Japan 1-0 Morocco
Highly-fancied Spain will not qualify for the knockout stages of the Olympic football tournament as Jerry Bengtson scored the only goal.
Bengtson's early header sunk a Spanish team featuring Manchester United's David de Gea and Chelsea's Juan Mata.
Meanwhile, Japan booked their place in the last eight of the tournament with a late goal from Kensuke Nagai to sink Morocco and damage the African side's hopes of qualification.
