ACT Brumbies players believe Laurie Fisher's decision to quit the club to coach in Britain will have a bigger impact than the shock departure of former World Cup-winning coach Jake White.

Fisher is set to leave Canberra one year into his two-year contract as the Brumbies' director of rugby to become Gloucester's head coach at the end of the Super Rugby season.

But Fisher's coaching partner Stephen Larkham has emerged as the man to take on more responsibility next year in a traditional head coaching role at the Brumbies.

It's understood the Brumbies have already set up a committee to decide the club's next coaching structure, with Larkham the candidate to be appointed on a longer-term deal as the leader of a more traditional coaching set up.

Larkham and Fisher have shared the coaching role this season, with Larkham leading a successful retention campaign, re-signing a host of Wallabies and is set to lead the team into the future.
