Disappointed Brentford boss Uwe Rosler accused his players of "throwing in the towel" in their 3-1 home defeat to in-form Preston.
The straight-talking former Manchester City striker admitted his Bees side were given a lesson in terms of power, strength and experience by North End, who made it six straight wins on the trot in Saturday's League One clash at Griffin Park.
A double from Neil Mellor either side of Iain Hume's wonder goal overshadowed Niall McGinn's effort as the Lilywhites emerged victorious.
Rosler said: "On our day, we can compete with and beat any side in this division but we made individual mistakes and once we got the equaliser we then failed to keep up the tempo.
"We got ourselves back into the game but in the second half, in particular, I was disappointed that one or two threw the towel in.
"Preston looked much fresher and although they don't have the attitude some of our players had, they are physically strong and competed for every ball."
