Sam Hutchinson's goal at the death for Sheffield Wednesday on Saturday was the first the Bees have conceded in three home games this season, and even on the road, they have only lost by the odd goal.
Not bad for a back four, half of which are as good as new to the Championship before (John Egan played one game on loan at Crystal Palace in 2012), in front of a keeper also new to this level.
He said: “To be fair, it was an unbelievable header right in the top corner, and if it's going to beat me and go in the top corner like that, sometimes you have to take your hat off.
“I did everything I could to keep the clean sheet, unfortunately today it wasn't to be. In terms of our performance, there's a lot to work on, but a lot to take out of it as well.
“We've got real resilience as a back four. We're not easy to break down and not easy to beat, which is something to take forward.
“If we continue in the same vein defensively and make some adjustments going forward, I'm sure we'll be firing on all cylinders before too long.”
After getting pummelled in the first half but somehow staying on level terms, Brentford took the lead through Lasse Vibe after the break, and managed to hold on until the third minute of injury time at the end of the 90.
Bentley added: “As everyone can see, they put us under a lot of pressure and we sucked it up, and I thought we defended well on the whole.
“Whether we deserved the goal or not I'm not entirely sure, but it gave us something to hang onto, although I think we put ourselves under too much pressure in the latter stages of the second half.
“I'm gutted about conceding the late goal, but on the whole it's not a bad point and could make a difference at the end of the season.”
