Sunderland loanee Jack Clarke has thanked Marcelo Bielsa for handing him his chance in professional football following his dismissal at Leeds United.
Clarke was handed his debut for the Whites by Bielsa at the age of just 17 as he came on as a substitute in a 1-1 Championship draw with Brentford.
Bielsa went on to hand Clarke several opportunities as he went on to make 25 appearances for Leeds in his maiden season in senior football.
