Ouattara, 23, scored 11 goals in 88 appearances for the Cherries since joining from Lorient in 2023.

Brentford confirmed the transfer is a club-record fee, surpassing the £30 million they spent on Igor Thiago last year.

“We’re really happy to get Dango in. He’s someone that we were aware of and surprised could be available and, once we knew that signing him might be a possibility, we really focused on trying to get him in,” said Brentford boss Keith Andrews.

“We liked his Premier League experience, even at his young age, and he just hasn’t found the rhythm yet because of a lack of consistent game time.”

Brentford have lost all of their manager, top scorer and captain from last season after finishing 10th in the Premier League.

Thomas Frank left to manage Tottenham, Bryan Mbeumo was snapped up by Manchester United and Christian Norgaard was signed by Arsenal.

Wissa could join that exodus, with Newcastle reportedly interested in the DR Congo international, who scored 19 Premier League goals last season.
