Lee Carsley's tenure as Brentford head coach started in disappointment as they fell to a 2-0 Championship defeat at home to Birmingham City on Tuesday.
Carsley, a former Birmingham midfielder, was promoted to the top job after Marinus Dijkhuizen was sacked just three months after being appointed, a 2-1 defeat at home to Sheffield Wednesday on Saturday proving the final nail in the coffin.
Michael Morrison headed home the first in the 71st minute, before Clayton Donaldson chipped in Birmingham's second deep into injury time.

Portsmouth were previously top but Paul Cook's side slipped to a 2-1 defeat at home to Exeter City, while Leyton Orient lost for the just the second time this term by the same scoreline at home to Carlisle United.
