Uwe Rosler expects another big test of Brentford's promotion credentials when they host Preston on Saturday.
The Bees bounced back from two straight defeats when they came from behind to beat fellow high-fliers Swindon 2-1 in midweek.
They now face a North End outfit unbeaten in four matches since Simon Grayson took over from Graham Westley.
"It will be another physical game," said Griffin Park boss Rosler. "They have not changed all their players, they will have a direct approach. We have to cope with that.
"We did that well in the second half against Swindon and it will be a tight game."
