Brentford stopper Daniel Bentley says he and his team-mates first half performance against Sunderland "wasn't good enough", writes Mark Ritson .

The Bees took the lead early on through Nico Yennaris' tap-in, but went into the break 3-1 down.

Brentford fans may have expected an easy win against a Sunderland side struggling in the bottom three, but the visitors punished them for sloppy mistakes.

And Bentley, at fault for the second, admitted it wasn't acceptable from the standards they set.

"But we didn't play to the conditions well enough, we didn't keep the ball well enough and invited pressure on ourselves.

"We gave away three sloppy goals, all of which could have been avoided.

"However, we've shown character and dominated the second half. I don't think Sunderland had a sniff and on another day we could have come away with three points.

"If we had avoided those goals in the first half, we don't leave ourselves in a position where we have a massive uphill task.
