Birmingham's poor form under Gianfranco Zola continued as they slumped to a 3-1 defeat at home to Brentford.
They took a first-half lead through Lukas Jutkiewicz but Scott Hogan equalised before missing a penalty. That did not prove costly though as David Davis deflected a Ryan Woods free-kick past his own goalkeeper and substitute Nico Yennaris added a late third.
Zola admitted that the second 45 minutes at St Andrews were the worst of his four games in charge, branding his players 'weak and fragile.'
'The second half performance has been the most disappointing so far,' the Birmingham manager conceded.
