Argentina got their Group B campaign at the Olympics up and running with a 3-1 victory over Iraq, with Thiago Almada, Luciano Gondou and Ezequiel Fernandez scoring.

Javier Mascherano's side made a losing start against Morocco on Wednesday, going down by a 2-1 scoreline in a chaotic match that featured almost 20 minutes of second-half stoppage time and a two-hour delay due to crowd trouble.

They bounced back against Iraq despite Aymen Hussein cancelling out Almada's opener, with Gondou and Fernandez on target in the second half in a deserved victory.

Argentina hit the front after 14 minutes as Julian Alvarez improvised to chest a deflected cross down to Almada, who lashed into the bottom-left corner on the volley. 

But Iraq grew into the contest and got their reward five minutes into first-half stoppage time, Hussein getting across his marker to nod Ahmed Maknzi's cross into the far corner.

Argentina were in the ascendency throughout the second half, though, restoring their lead shortly after the hour mark. Iraq goalkeeper Hussein Hasan got caught under Kevin Zenon's cross as Gondou headed home at the far post.

They wrapped up the points when Fernandez scored the pick of the goals with five minutes remaining, the midfielder curling a left-footed shot into the top-left corner after clever play from Almada and Zenon.

The Albiceleste, Iraq and Morocco are now all level on three points with one game remaining, with Ukraine pointless ahead of facing the Atlas Lions later on Saturday.

Data Debrief: Almada pulls the strings

Almada was part of Argentina's 2022 World Cup-winning squad and attracted plenty of admiring glances from European clubs while with Atlanta United, only to join Botofogo for an MLS-record fee earlier this month.

The Brazilian giants have every right to be pleased with their purchase.

As well as firing in the opener on Saturday, Almada managed a game-high three chances created and 30 passes in the final third. A sumptuous backheel in the build-up to Fernandez's goal provided another glimpse of his quality. 

Jordan fought back to beat 10-man Iraq 3-2 and clinch their place in the Asian Cup quarter-finals on Monday.

Iraq's Aymen Hussein turned from hero to zero as, moments after putting Iraq ahead, he was sent off, having received a second yellow card for excessive celebrations at Khalifa International Stadium.

Down to 10 men, Iraq could not withstand Jordan's fightback and conceded twice in stoppage time to end their hopes of winning the competition for a second time.

Hussein struck in the 76th minute to spark wild celebrations, including him sitting cross-legged on the field and mimicking eating.

Iraq's joy soon turned to frustration, though, when referee Alireza Faghani booked Hussein for a second time.

It got worse for the 2007 champions when Yazan Al Arab levelled in the fifth minute of added time, with Nizar Al Rashdan going on to drill in a winner two minutes later.

Jordan advanced as one of the best third-placed teams and took the lead in the first minute of first-half stoppage time through Yazan Al Naimat.

Suad Natiq equalized for Iraq prior to Hussein's fifth goal of the tournament sparking the chaotic finale.

Jordan will play tournament debutants Tajikistan in the last eight.

In the day's other match, Akram Afif delivered again for Qatar as the hosts and defending champions overcame Palestine 2-1.

Afif has established himself as one of the stars of the tournament, and if he can keep up this form he may yet achieve his ambition of joining a European club.

The forward struck from the penalty spot in the 49th — his fourth goal of the Asian Cup — as Qatar came from behind at Al Bayt Stadium, with Hassan Al Haydos having cancelled out Oday Dabbagh's clinical finish.

Qatar will play either Uzbekistan or Thailand for a place in the last four.

Japan got their Asian Cup campaign back on track by advancing to the knockout stage with a 3-1 win against Indonesia on Wednesday.

The pre-tournament favourites surprisingly lost to Iraq in their second Group D match last week to leave their hopes of winning a record-extending fifth Asian Cup title in jeopardy.

But any concerns over facing an early exit were swept away at Al Thumama Stadium after two goals from Ayase Ueda put the four-time champions on course for victory.

Justin Hubner scored a late own goal and Sandy Walsh pulled one back for Indonesia in added time.

It took Ueda just six minutes to settle any nerves Japan's players and fans might have been feeling going into their final group game.

The Feyenoord striker had won the spot kick after being fouled by Jordi Amat and fired his shot into the corner beyond Indonesia goalkeeper Ernando Ari Sutaryadi to open the scoring.

He doubled Japan's lead in the 52nd minute and when Hubner diverted another effort from Ueda into his own goal in the 88th the win looked beyond doubt.

Walsh scored a consolation in added time and Indonesia, on three points, will have to wait to see if they advance as one of the best third-placed teams.

While Japan safely secured their progress, it was Iraq who advanced as group winners after substitute Aymen Hussein scored from the penalty spot in the 12th minute of stoppage time to beat 10-man Vietnam 3-2 in a thrilling clash.

Having already missed one penalty after coming on as a half-time substitute at Jassim Bin Hamad Stadium, Hussein converted from the spot deep into stoppage time to maintain Iraq’s perfect record in Group D.

Hussein is the tournament's leading scorer with five goals and that record might have been even better had he not struck the post with his earlier penalty against Vietnam.

He still managed to have a key impact on the match with two goals as the 2007 champions came from behind to make it three wins out of three.

Vietnam had taken the lead through Bui Hoang Viet Anh in the 42nd minute, but Khuat Van Khang was sent off in first-half stoppage time for a second yellow card.

It took only two minutes of the second half for Rebin Solaka to even the score for Iraq and Hussein headed his team in front 17 minutes from time.

Hussein failed to score from the spot when firing against the post and that miss looked to be costly when substitute Nguyen Quang Hai levelled the game in the 91st minute.

That was until Hussein was given the chance to make amends for his earlier penalty, and he made no mistake from the spot on this occasion.

Aymen Hussein scored both goals as Iraq shocked tournament favourites Japan 2-1 to claim a place in the knockout stage of the Asian Cup on Friday.

Hussein struck twice in the first half at Education City Stadium, with a 93rd-minute header from Wataru Endo proving to be too little, too late for Japan.

The famous win lifts Iraq, the 2007 champions, to the top of Group D with six points from two games and guarantees them a spot in the round of 16. 

Four-time winners Japan, Asia's highest-ranked team at 17, are second with three points.

Iraq took the lead after just six minutes when Japan goalkeeper Zion Suzuki palmed Ali Jasim's cross from the left straight to Hussein, who headed it home.

Japan streamed forward in search of an equaliser but Iraq defended in numbers before doubling their lead in first-half added time as Hussein headed in Aymed Yahya's cross. The goal was given following a VAR review to check if the ball had rolled out of play in the build-up.

It looked like Japan had been awarded a penalty 10 minutes into the second half as Takuma Asano was judged to have been fouled by Rebin Sulaka. However, referee Khalid Al-Turais overturned his original decision after viewing the pitchside monitor.

Liverpool midfielder Endo eventually got Japan within a goal in added time after goalkeeper Jalal Hachim failed to collect the ball but it was not enough to prevent his country's first group-stage loss at the Asian Cup since 1988.

Vietnam play Indonesia in the other Group D game on Friday, before Hong Kong meet Iran in Group C.

Lee Kang-in's individual brilliance inspired South Korea to a 3-1 victory over Bahrain in the Asian Cup on Monday.

Used to being overshadowed by Kylian Mbappe at club level and Son Heung-min on the international stage, Paris Saint-Germain's Lee took centre stage at Jassim Bin Hamad Stadium.

While Son missed a golden chance late on and was also booked for diving, Lee scored two picture-perfect goals to get South Korea off to a winning start in the competition the country has not won since claiming back-to-back titles in 1956 and 1960.

Not that he was comfortable with the spotlight.

"I would just like to say and highlight that it is not about individual performance. It's not just about my two goals. All the goals we score are very important for the team," he said after the Group E match.

His coach Jurgen Klinsmann was also restrained in his praise.

"If you score two in the opening game of the Asian Cup for us you deserve to be man of match and [it was] a very good performance. But I have to keep him on the ground every day," he said with a smile.

The game was tied at 1-1 when Lee took control, giving South Korea a 2-1 lead in the 56th minute with a left-footed shot from around 30 yards.

He was equally clinical as he scored his second goal 12 minutes later when showing sharp footwork and curling the ball into the bottom corner.

Hwang In-beom had given South Korea a first-half lead, but Bahrain equalised six minutes after the break through Abdullah Al Hashash.

Jordan sit top of Group E on goal difference after a 4-0 win over Malaysia.

Mahmoud Al Mardi and Mousa Tamari scored two goals each in the match at Al Janoub Stadium.

Jordan raced to a 3-0 half-time lead, with Al Mardi on target twice and Tamari scoring from the spot. The latter, who also had a goal disallowed by VAR, doubled his tally in the 85th minute.

In Group D, Iraq moved level with Japan on three points thanks to a 3-1 defeat of Indonesia.

Goals from Mohanad Ali, Osama Rashid and Aymen Hussein secured victory at Ahmad Bin Ali Stadium, while Marselino Ferdinan netted for Indonesia, who are making their first appearance in an Asian Cup in 16 years.

Russia defeated Iraq 2-0 on Sunday in their first home international since the country invaded Ukraine.

European and global football governing bodies UEFA and FIFA announced in February 2022 that Russia's international and club sides would be suspended from their competitions.

Russia have played Kyrgyzstan, Tajikistan, Uzbekistan and Iran in friendlies since then, but not since November 2021 had they played on home soil.

Anton Miranchuk gave Russia the lead against Iran early in the second half at the Gazprom Arena and Sergey Pinyaev added a second just before the hour mark.

The venue in Saint Petersburg had been due to host last year's Champions League final, but it was instead held at the Parc des Princes in Paris in wake of Russia's military actions.

Costa Rica cancelled their World Cup warm-up match against Iraq due to an issue over passports.

Luis Fernando Suarez's side were set for one final test before they begin their Group E campaign against Spain in Qatar next Wednesday.

Ahead of travelling to the Gulf State on Friday, Costa Rica had been staying in Kuwait, with the intention to cross into Iraq for Thursday's friendly.

But having travelled to the border on Wednesday, a request to have their passports not stamped was not honoured by local authorities, forcing them to return to their camp.

"The match against Iraq was suspended," Costa Rica's Football Federation stated.

"An agreement that was made with the non-stamping of passports was not respected and for this reason it was decided not to enter Iraq and cancel the match."

Costa Rica are competing in their third consecutive tournament, having reached a best-ever finish at Brazil 2014 by progressing to the quarter-finals.

A dismal Russia 2018 campaign saw them eliminated in the group stages, with Suarez's side likely to face a tough test in a group that also contains Japan and Germany.

Mexico were posed very few problems by Iraq in their first World Cup warm-up game, winning 4-0 in Girona on Wednesday.

Although many countries have been unable line up pre-tournament friendlies due to the awkward timing of Qatar 2022, El Tri will travel to the Middle East with two games under their belts.

Their first may not have been particularly competitive, but it did the job in providing an opportunity to build sharpness and confidence ahead of the tournament, with Mexico dominant throughout.

The first half was especially one-sided, but Tata Martino's men could only find the Iraq net once via Alexis Vega's simple finish following fine work by Jesus Gallardo at the end of a rapid counter.

Mexico's fortunes improved after the break, with Rogelio Funes Mori smashing into the roof of the net early in the second half, and it was 3-0 just past the hour – Gallardo unleashing an emphatic half-volley that gave the goalkeeper no chance.

The scoring was completed late on when a handball offence in the box led to a penalty, and Uriel Antuna coolly converted.

Mexico's second and final pre-World Cup game is against Sweden on Wednesday, with El Tri then set to face Poland, Argentina and Saudi Arabia in Group C.
