Although sides including France, Argentina and Spain are thought to be the favourites for gold, these two sides could be considered as the dark horses: in particular Morocco.
They are used to defying the odds having reached the semi-finals of the 2022 FIFA World Cup in Qatar, narrowly being beaten 2-0 by France in that game and eventually losing to Croatia in the third-place play-off.
This current side nearly had a perfect group stage having picked up two wins and a defeat. The 2-1 victory over Argentina signalled their intent to go deep in the competition but they were unable to get past Ukraine having fallen to a 2-1 defeat. They restored hope last time out though after triumphing 3-0 over Iraq.
The USA had an identical run of results in the group stage with six points on the board from three games. There were signs of optimism despite losing 3-0 to hosts France in their first game and they showed their credentials with a commanding 4-1 win over New Zealand.
They made sure of qualification in their last outing with a 3-0 victory over Guinea: Djordje Mihailovic opened the scoring before Kevin Paredes netted a brace.
Which of these two sides can reach a historic semi-final and step closer to the final?
Team News
There are no injury concerns for the Moroccans who could name an unchanged team from their win over Iraq.
It looks like Abde Ezzalzouli will start having impressed in that famous win over Argentina.
One concern for Marko Mitrović's side is midfielder Gianluca Busio who they are awaiting news on the extent of his leg injury that was sustained in the win over Guinea.
The three overage players, Mihailovic, Miles Robinson and Walker Zimmerman, are expected to start once again and the return of Busio could coincide with Griffin Yow dropping out of the side.
Key Players
United States - Djordje Mihailovic
One of the United States' star men in the tournament so far, Mihailovic has been a mainstay in the side with three appearances to his name as well as two goals and one assist in that period.
He calmly converted a penalty in the 4-1 thumping of New Zealand as he played a part in ensuring the Americans didn't bow out at the first opportunity and in the win over Guinea last time out, a sublime free-kick opened the scoring.
Simultaneously, the 25-year-old became the first Major League Soccer (MLS) player to score in consecutive matches for the United States Olympic team since Sacha Kljestan in 2008 in Beijing.
In particular against New Zealand, his work rate stood out and he has shone in this United States side. Mihailovic is currently at the Colorado Rapids where he has netted ten goals and registered six assists in 21 matches so far this year.
Morocco - Achraf Hakimi
One of their key men in the success of the last World Cup, Achraf Hakimi is looking to emulate that success in this Olympic Games.
With responsibility on his shoulders having been appointed captain, he has led by example and will be a regular in the right-back position for however far Tarik Sektioui's side progress.
Considered by many to be one of the best right-backs in world football, he's now heading into his fourth season at PSG and in that time, he has won Ligue 1 on four occasions but is yet to pick up any major European honours since leaving Real Madrid.
He is a threat in the final third and is the epitome of the modern-day right-back - the ability to get up and down the flanks by also creating chances for the team and the 24-year-old could have the winning experience Morocco need to progress to the latter stages of these Olympic Games.
Likely line-ups
Mohamedi; Hakimi, Boukamir, El Azzouzi, El Ouahdi; Targhalline, El Khannouss, Richardson; Akhomach, Rahimi, Ezzalzouli
United States
Schulte; Tolkin, Zimmerman, Robinson, Harriel; Busio, Tessmann, Mihajlovic; Paredes, McGuire, Aaronson
