UWE ROSLER slammed the shoddy defending which cost his team a share of the spoils at Yeovil.
The Brentford boss could not hide his frustration after his team were undone two minutes from time to suffer a rare away reverse.
"That was not a professional level of defending," said the German. "We should have dealt with the situation much better.
"Today was a big blow for us. The way we started and the way we played the game, we were one nil up but we lost it.
"We have to learn - so when we burn our fingers we have to make sure we don't burn them again."
Rosler added: "I thought we learnt a lesson against Colchester, but it looks like we have to go through more pain."
