Brennan joined Team Visma | Lease a Bike’s WorldTeam at the beginning of 2025, after needing only one year with the Dutch team’s development squad to convince the cycling world of his abilities. The British top talent, who has a background in track cycling, immediately won his first two races of the season and a stage in the Giro NextGen. He also stepped onto the podium at the Circuit de Wallonie, a 1.1-level race.

This season, Brennan continued to surprise both himself and the team in a positive way. His racing calendar was adjusted several times after he repeatedly showed he was capable of competing at a higher level. He started winning at the Tour des 100 Communes and the GP de la Ville de Lillers, races in which he still lined up alongside the Development Team. He then claimed victories at .Pro level in the GP de Denain and at WorldTour level in the Volta a Catalunya. His win tally ultimately stopped at fourteen victories in 2025, twelve of which were at professional level.

“Matthew has really surprised us in a positive way this season,” said Head of Racing Grischa Niermann. “Of course, we already knew him well, because he came through our own ranks. As a team, we constantly adapted to his level and offered him races and challenges tailored to him. He has made big steps in his development this season, but still has a lot to learn. We see working with him as a long-term project, and that is why we are so happy that he feels the same way. In the coming years, we want to help him take the step to the highest level in cycling. He may continue to surprise us.”

Brennan himself agrees with Niermann’s words and cannot imagine a better place to further build his cycling career. “The environment in this team is so unique: it is partly thanks to the team that I have already been able to develop myself so much. Everyone can help me become a better rider, both the staff and the other riders. And on top of that, I feel the trust I need here. I am happy here and very grateful for the opportunity to take the next steps in my career over such a long period and without pressure.”
