A brilliant bit of skill by Sergi Canos leaves Jack Robinson in trouble, but Brentford's move breaks down.

Away from Loftus Road and tonight's action, Wolves are currently flying high at the top of the Championship table.

Nuno Espirito Santo's side are currently four points clear of second placed Cardiff and averaging more than two goals a game.

They've won their last five and appear to be the team to beat this season, and keeper John Ruddy says Wolves have 'too much quality' for the rest of the division if they keep outworking their rivals.
