Vincent Aboubakar scored two penalties as Cameroon came from behind to beat Burkina Faso 2-1 in the opening match of the delayed 2021 Africa Cup of Nations.

After twice being moved due to climate issues and COVID-19, the tournament finally got under way at Olembe Stadum in Yaounde on Sunday.

Burkina Faso took the lead in the first game in Group A, which also includes Ethiopia and Cape Verde, thanks to Gustavo Sangare's back-post volley after 24 minutes.

Bertrand Traore had a header cleared off the line in the build-up to that opening goal, but he gave away a penalty for a trip on Andre-Frank Zambo Anguissa at the other end.

Aboubakar converted following a long VAR review and the Cameroon captain was on target again from the spot eight minutes later after Issoufou Dayo slid in on Nouhou Tolo to concede another penalty.

VAR intervened to deny an offside Aboubakar when he thought he had bundled in a third in the second half, but two goals proved enough for Cameroon to get off to a winning start.

We may only be a week into 2022, but the first major international football tournament of the year is on the horizon, with the Africa Cup of Nations kicking off on Sunday.

It's been a long time coming as well – it was initially due to take place in June and July 2021 but was brought forward to January 2021 due to concerns about the weather. It then had to be pushed back a year due to the coronavirus pandemic.

Of course, fans and teams have had to put up with the usual posturing from those at certain clubs regarding the inconvenience of relinquishing players in the middle of the season, but despite that there remains a healthy selection of big names.

In fact, given the standard the likes of Mohamed Salah, Sadio Mane, Riyad Mahrez and Achraf Hakimi usually play at, some might even argue this is one of the highest-quality groups of players to feature at a single AFCON.

But the beauty of every international tournament is that there's more to them than the big names – there are plenty of promising younger players looking to impress for a global audience.

Kamaldeen Sulemana, 19, winger – Ghana

Hold on to your seats! Kamaldeen is sure to ramp up the excitement at AFCON, such is his rather chaotic approach to attacking – and acrobatic celebration. The teenage winger is immensely tricky and agile, with his 246 take-on attempts in the 2020-21 Danish Superliga nearly twice as many as anyone else – to put that into context, only Lionel Messi managed more (261) in the top five leagues. He's carried that into Ligue 1 following his move to Rennes, with his average of one shot involvements from a ball carry every 43 minutes being the second best in Ligue 1 (min. 900 minutes played) after Kylian Mbappe – that's obviously pretty good.

Ibrahim Sangare, 24, defensive midfielder – Ivory Coast

While good performances at AFCON alone may not be enough for players to convince big clubs they're worth a punt on, showing promise might just get a few more eyes on them. Sangare is definitely one of those who could put himself 'in the shop window'. The PSV midfielder has a lot about him, particularly when it comes to defending. In this season's Eredivisie, only three players (at least 500 minutes played) have averaged more than his 3.4 tackles per 90 minutes, while he ranks fifth for interceptions frequency (2.5) and third for middle-third recoveries (5.7). He's also technically proficient and happy on the ball, with only three players attempting more passes (81.1) on a per-90-minute basis than him.

Hannibal Mejbri, 18, attacking midfielder – Tunisia

A former France youth international, Mejbri may have only declared for Tunisia in 2021 but this will already be his second international tournament. The Manchester United midfielder started all six of Tunisia's games as they reached the final of the Arab Cup in December, eventually losing to Algeria in the final. Hannibal may not feature quite as prominently in a full-strength squad, but the midfielder possesses the kind of off-the-cuff abilities that endear him to fans – if not opponents. He is known to be targeted for fouls when playing for United's second team, such is his natural talent.

Ilaix Moriba, 18, central midfielder – Guinea

2021-22 hasn't quite gone as Moriba presumably thought it would. He left Barcelona after failing to agree a new contract, despite having broken into the first-team setup at Camp Nou. The midfielder had shown exceptional promise, particularly on the ball – he averaged 3.2 dribbles per 90 minutes, a total bettered by only four team-mates, and boasted a success rate of 89.3 per cent, with only Miralem Pjanic bettering him. The €16million signing has played just twice in the Bundesliga since the move to Leipzig and will surely be relishing some competitive action.

Edmond Tapsoba, 22, centre-back – Burkina Faso

If Burkina Faso go on to have a good tournament, Tapsoba will almost certainly have had something to do with it. The centre-back is an extremely elegant player for someone roughly the size of a small building and whose name sounds like a hipster bar, and at club level he performs a vital function in getting Leverkusen on the front foot, with his 13.5 progressive ball carries in the Bundesliga this term second only to Alphonso Davies. If he can translate that to the international stage, Burkina Faso will have a real weapon in the middle – even if he doesn't, he'll still give them aerial threat at set-pieces.

Abdul Fatawu Issahaku, 17, forward – Ghana

The case of Issahaku is a rather intriguing one. Transfer rumours in 2021 suggested Liverpool had signed him for £1.5million, but that soon turned out to be false. He remains in his native Ghana, but the exciting attacker has seemingly done enough to earn a shot at international level despite being just 17 – he's the second-youngest player at the tournament. But he's used to that sort of situation. After all, before he'd even turned 17 in March he was named Player of the Tournament at the Under-20 Africa Cup of Nations. While that Liverpool move never materialised, he's got himself another opportunity to shine.

After delays, postponements and date changes aplenty, the Africa Cup of Nations will finally start on Sunday, as hosts Cameroon take on Burkina Faso.

Group A will also pit Ethiopia and Cape Verde against each other on the opening day, with both eyeing up the possibility of staking their claim for a qualification spot behind favourites Cameroon.

But, as may have been expected of a tournament that has had more than its fair share of issues in the build-up, another problem has reared its head on the eve of the big kick-off.

Cameroon v Burkina Faso (16:00 GMT)

Burkina Faso are questioning the validity of the COVID-19 testing that was done on their squad, with "four or five" players and head coach Kamou Malo returning positive results.

They claim an unknown medical team turned up at their hotel to test the team and staff, but they refused to take them after the African Football Confederation (CAF) confirmed the people who had showed up were not sent by tournament organisers.

When the CAF delegation did show up, four positive tests came back and one was inconclusive, with Burkina Faso now demanding new swabs be taken.

Captain Bertrand Traore told reporters: "It's a scandal, we cannot be deprived of first-team players 24 hours before the match.

"The authorities must review the organisation. We cannot accept this decision. We can redo tests of our positive players."

Either way, Cameroon know the pressure is on for them to claim a sixth AFCON title, with this their first tournament as hosts in 50 years.

One to watch: Andre-Frank Zambo Anguissa (Cameroon)

AFCON has never been short of flair players, and in Zambo Anguissa Cameroon have a player really capable of getting fans off their feet. The Napoli man is a fascinating midfielder to watch due to his ability running with the ball. In Serie A this season, his 65.9 per cent dribble success is bettered by only seven midfielders (min. 25 dribble attempts, 500 minutes played), playing an important role in getting the Partenopei out of tight situations and onto the front foot.

Ethiopia v Cape Verde (19:00 GMT)

Four of the six teams to finish third in their group will go through to the next stage, so while that takes away some of the jeopardy for the best teams, it also provides more of a chance for those nations who would not otherwise expect to get far.

With Ethiopia and Cape Verde avoiding Cameroon on matchday one, both will fancy their chances of getting off to a positive start – and three points could be all they need to qualify as one of the best third-placed teams.

Cape Verde have been impacted by a COVID-19 outbreak, though, with coach Roberto Lopes among those infected.

Ethiopia are seemingly in better shape, with coach Wubetu Abate keen to show off their gifted young players.

"We respect our opponents, but we are confident in our talent," he said. "Our goal is not to just participate, but to show the world that Ethiopia has young talented players who can surprise."

One to watch: Amanuel Gebremichael (Ethiopia)

Ethiopia lost talisman – and one of just two foreign-based players – Shimelis Bekele to injury, meaning they will need others to step up. Most of the goalscoring burden is on the shoulders of Getaneh Kebede, but Gebremichael has a skillset that should make him a threat, boasting plenty of speed and the ability to get in behind defences.
