African stars who soared and signings that could flop: The transfers defining the summer window

The offseason transfer window has shut for many leagues around the world, and Africa’s players were at the centre of several of the biggest deals.

From Manchester City’s huge investment in Morocco’s Ayyoub Bouaddi to a series of ambitious Premier League moves, African footballers featured prominently in a summer market that produced both eye-catching successes and some head-scratching decisions.

While some transfers already appear destined for success, others carry significant risks, whether because of inflated fees, difficult environments or the enormous leap required by young players.

Bouaddi the jewel of the window

For sheer potential, few African transfers can match Ayyoub Bouaddi’s move from Lille to Manchester City.

City reportedly paid an initial £81.3 million for the 18-year-old, making him the most expensive teenage player in world football. The size of the investment reflects City’s belief that the Morocco international can become a cornerstone of their midfield for years to come.

Bouaddi combines technical quality, intelligence and maturity with considerable experience in French and European football. The challenge will be adapting to the demands of English football and, eventually, shouldering expectations associated with succeeding Rodri.

The fee creates pressure, but Bouaddi possesses the qualities to justify it.

Marmoush gets a fresh start

Omar Marmoush’s switch from Manchester City to Tottenham could prove one of the window’s most intriguing moves.

The Egypt international struggled to reproduce the extraordinary form he displayed at Eintracht Frankfurt after moving to England, although questions remain over whether City’s system brought out his best qualities.

At Tottenham, Marmoush could find a more suitable environment. His game thrives on transitions, attacking space and operating between central and left-sided positions.

If Roberto De Zerbi can provide that freedom, the 27-year-old has the opportunity to revive the form that made him one of Europe’s most dangerous forwards in Germany.

Oulai, Saibari among the rising stars

Ivory Coast midfielder Christ Inao Oulai is another player whose ceiling could be enormous.

The 20-year-old impressed at the World Cup with his technical ability, confidence under pressure and defensive maturity. Fiorentina have taken a considerable gamble, but the move could pay off handsomely if Oulai continues his rapid development.

Morocco’s Ismael Saibari, meanwhile, has already offered an encouraging glimpse of what could be ahead at Bayern Munich.

The midfielder joined from PSV Eindhoven for €50 million and made an immediate impression, providing two assists during a 29-minute debut against Stuttgart.

His aggression, technical ability and positional versatility should make him a valuable option for Bayern, while his combination play with Harry Kane could become particularly important.

Sangare and Mendy making instant statements

Mamadou Sangare has wasted little time making an impression at Brentford.

The Mali international scored on his debut against Tottenham and played a major role in the Bees’ impressive attacking display. Although his defensive qualities were a major reason for his recruitment, Sangare offers considerably more than simply ball-winning.

If his early performances are an indication, a move to one of Europe’s elite clubs could be within reach before long.

Senegal’s Nobel Mendy has also made an encouraging start after joining Hull City.

The 22-year-old scored on his debut during Hull’s historic win over Manchester United and has looked comfortable dealing with the physical and psychological demands of English football.

Onyedika and Jackson offer contrasting gambles

Raphael Onyedika could prove one of the bargains of the window.

The Nigeria international left Club Brugge for Eintracht Frankfurt for only €9 million, finally earning a move to one of Europe’s major leagues at the age of 25.

With a Belgian league title, Champions League experience and an AFCON semi-final appearance already on his CV, Onyedika arrives with both experience and room for further growth.

Nicolas Jackson’s move to Aston Villa is harder to assess.

Villa have paid a club-record £65 million, meaning expectations will be high, particularly in front of goal. Yet reducing Jackson’s contribution to his finishing would overlook his ability to stretch defences, press aggressively and create opportunities.

A reunion with Unai Emery could help him rediscover the form he showed at Villarreal, but Villa will ultimately demand goals to justify the investment.

Mbaye carries a huge price tag

Not every big-money move inspires the same confidence.

Ibrahim Mbaye’s £47 million transfer to Aston Villa represents a significant gamble on potential. The teenager made his competitive Paris Saint-Germain debut in August 2024 and featured 24 times last season, but never secured a regular first-team role under Luis Enrique.

His contribution of just five goals last term also underlines the uncertainty surrounding the deal.

Mbaye undoubtedly has considerable upside, but Villa have paid a premium for projection rather than established production. Playing regularly for a Champions League club brings another level of expectation.

Yirenkyi faces a brutal test

Ghana international Caleb Yirenkyi faces a different challenge at Coventry City.

His credentials are strong. The 20-year-old was named Danish top-flight Young Player of the Year last season and also made the league’s Team of the Season.

But moving from Nordsjaelland directly into the Premier League is a significant step, particularly with Coventry expected to spend much of the campaign fighting relegation.

For a young player, regularly playing for a team under pressure and losing matches can be an unforgiving environment. Whether Coventry can provide the platform for Yirenkyi’s development while benefiting from his considerable talent remains one of the season’s intriguing questions.

Cherif and Yohanna face similar concerns

Sidiki Cherif’s £20 million move to Coventry also raises questions over timing and value.

The forward has shown flashes of promise but has scored only eight senior league goals in 57 appearances. The combination of his transfer fee, limited experience and the pressure surrounding a newly promoted team could make his adaptation difficult.

Zadok Yohanna’s move to Brighton presents another gamble on potential.

The Nigerian only moved from Ikoh Allah Academy to AIK in June 2025 and had just 13 senior league appearances before making his Brighton debut against Aston Villa on August 23.

Brighton have built a reputation for identifying young talent, and Yohanna could ultimately prove another success story. However, the Premier League represents an enormous leap, and the immediate pressure to perform may not provide the ideal environment for such an inexperienced player.

For every Bouaddi or Saibari whose enormous potential could be realised, the summer window has also produced transfers where the fee, timing and destination leave considerably more questions than answers.
