Manager Mark Warburton admits his Brentford side his were off the pace during this afternoon's defeat at Birmingham City.
The Bees looked a shadow of the side at St Andrews of the one which has put Bournemouth and Blackpool to the sword in the past week.
A James Tarkowski own goal, under pressure from former Bee Clayton Donaldson, was all that separated the sides in a scrappy encounter.
Warburton said: “We lacked a bit of quality today and we didn't take care of the ball. We had a lot of possession but lacked a bit of care with the final ball. The pitch made it a challenge too.
“It's a tough, tough league, and while there are still a lot of points to be played for, it doesn't matter what the rest of the top eight are doing if we're beaten by the teams below us.”
Liam Moore came straight in at centre back for a second Bees debut, while Stuart Dallas kept his place at left back despite the return of Jake Bidwell from suspension.
Warburton added: “While we felt we had the pace to hurt them up front, we also knew they had the pace to up front to hurt us too, and Liam is a strong, quick and powerful defender.
“We also know all about Clayton Donaldson from his time with us. He is also strong and powerful, works the channels and is difficult to play against. He got across the front of our defender, and it's a ball into our box we didn't deal with.
“Stuart Dallas has done really well, and while Jake Bidwell has been tremendous to get the amount of games under the belt at his age as he has, it's about doing the right thing by the players and sending out a message about consistency.”
