"When I first saw him, I thought to myself: 'Who on earth is this player?' laughs Youness Bengelloun as he remembers Mamadou Sangaré. With the transfer window in full swing in July 2025, the former Manchester City scout and agent was not expecting to come face to face with a "footballing alien", but that proved the case during a visit to Rapid Vienna's training ground. A few weeks later, Sangaré moved to Lens for around €5m. "He was impressive and what struck me was his technique and his work rate," Bengelloun says.

That's more or less the impression Sangaré has made at every club he's played for, including Brentford, for whom the Mali midfielder signed, from Lens, for a club-record £39m at the start of August. The 24-year-old excelled in his debut against Tottenham a few weeks later, dominating the centre of the pitch and providing the assist for Keane Lewis-Potter's opening goal, and has featured in every game this season, with Brighton up next. "I gave him his debut for Mali in September 2024, against Mozambique. He made an immediate impact," says Sangaré's former international manager Tom Saintfiet. "He's every manager's dream player."

Sangaré's rise began at Association Sportive Aboubacar Coulibaly (ASAC). A small club based in the Faladié neighbourhood of Bamako, Mali's capital, became a home from home at the age of six. Even then, his strength of character, work ethic and desire to succeed were clear, and immediately impressed his coach at the time, Bakary Coulibaly. "He lived not far from the ASAC pitch, so he'd come and play every day," Coulibaly says. "Right from the start I could see that Mamadou had great potential. He played as a right midfielder and was already technically better than the others.

"What surprised me most about Mamadou was that he always wanted to win. Even then he was very demanding of himself and his teammates and acted like a leader. When the team was struggling he was always looking for a solution to help us win."

Setting high standards and taking personal responsibility are sides of Sangaré that Saintfiet recognises. "He manages everything in his professional life," says the 53-year-old Belgian. "He controls his time for eating, sleeping, training … some people go to nightclubs to clear their heads, but he lives like a professional 24 hours a day.

"I remember one day, Yves Bissouma asked Mamadou what his favourite position on the pitch was. Mamadou answered that he wanted his own. I'll never forget that moment because it shows he had enormous confidence in his own abilities. But he's not arrogant; he's very shy. Very laid-back."

Saintfiet, who managed Mali from 2024 to 2026, adds: "When I think of Mamadou, I think first and foremost of his personality. He's never nervous, he always stays calm. He's always in control of the situation. When he receives the ball surrounded by three players, he'll keep his cool and he'll manage to find the pass to get out of it".

Sangaré progressed from ASAC to Yeelen Olympique before leaving Mali for Europe in September 2020, joining RB Salzburg after catching the eye of scouts from the Austrian club via video footage. There came various loan spells before a permanent move to Rapid Vienna in July 2024, and then on to Lens the following August, with Sangaré's one and only season at the French club a memorable one. Not only did he play a key role in Lens winning the Coupe de France but, in the process, he also picked up the Marc-Vivien Foé award, which recognises the best African player in Ligue 1.

Last season Sangaré took part in his first Africa Cup of Nations, where he helped Mali reach the quarter-finals. "The match during which he was the most impressive was against the Comoros [in the group stages]," says his fellow Mali midfielder, Lassana Coulibaly. "The first time we had seen him in training we all noticed he had that extra something. But in that match he was absolutely incredible".

Saintfiet was impressed with Sangaré's performance against the hosts Morocco, also in the group stage, and especially by his attitude beforehand. "I asked him to play on the right flank so we could field five midfielders. When you ask certain players to play in different positions, they often tell you it's not their natural role and that they don't feel comfortable. But when I spoke to Mamadou about it he immediately said: 'OK coach, I'll play wherever you want for the good of the team. I'll do my best. He is a loyal player who has always done everything he could to help me."

Brentford are the latest recipients of Sangaré's capabilities, on and off the pitch, and Saintfiet is sure they won't be the last. "I reckon he can play at an even higher level," he says. "He won't stop at Brentford."
