Yaw signed with Brentford on a two-year scholarship with a club option of a one-year professional contract.
The midfielder has previously played for Northampton’s Pro Direct Academy.
Yaw bases his game off Thiago Alcântara and Andrés Iniesta and says if he wasn't a footballer he would want to be a football coach.
His proudest football moment was signing with the Bees and his first football memory was the 2010 World Cup being on in the background at his old house.
