Chris Wood scored on his full debut as Burnley beat Crystal Palace to move into the top half of the Premier League table and increase the pressure on Eagles boss Frank de Boer.
Clarets record signing Wood, who scored the equaliser at Tottenham after coming on as a substitute two weeks ago, seized on a horrendous back-pass from Lee Chung-yong before shooting past Wayne Hennessey in just the third minute at Turf Moor.
It was one of only two attempts on target by the home side, who conceded the greater share of possession and territory to their opponents.
But Palace – lacking in composure and confidence – were unable to capitalise on the chances that fell their way, with Scott Dann seeing two efforts from close range blocked on the line and heading a sitter wide in the closing stages.
They remain without a league goal or point this season under Dutchman De Boer, chronically short of confidence and second bottom of the division.
They are also the first side in 93 years to lose the first four matches of a top-flight season without scoring a goal, since Preston in 1924.
Burnley have seven points and are up to seventh in the table, although it was not all good news as goalkeeper Tom Heaton was forced off with an arm injury after falling awkwardly in the first half.
