Brentford maintained an unbeaten start to their first Premier League season with a goalless draw against Crystal Palace at Selhurst Park.
The Eagles had the better of the chances in Patrick Vieira's first home game in charge, with debutant Conor Gallagher hitting the inside of the post early on.
Captain James McArthur then saw a curling effort from the edge of the box tipped away by David Raya after the break as the Eagles pushed for a breakthrough.
The best opportunity for Thomas Frank's Brentford, who beat Arsenal in their opening game last weekend, came when Bryan Mbeumo's free-kick from out wide clipped the top of the crossbar.
A return of four points and two clean sheets represents a fine start to what is their first top-flight campaign for 74 years.
