Tottenham Hotspur sank to a third successive Premier League defeat as first-half goals by Raul Jimenez and Leander Dendoncker gave Wolverhampton Wanderers a 2-0 away win to put them into seventh place on Sunday.
After losing 3-2 at home to Southampton in midweek, Tottenham desperately needed a response to boost their top-four ambitions, but defensive errors cost them dear.
Jimenez volleyed in after six minutes following a panicky punched clearance by Tottenham keeper Hugo Lloris and the Frenchman hardly covered himself in glory when Dendoncker doubled Wolves' lead 12 minutes later.
Lloris redeemed himself a little to prevent Wolves adding to their advantage before the break but Tottenham left the pitch at halftime to boos on a rain-sodden north London afternoon.
Tottenham improved in the second half but the closest they came was a deflected Harry Winks shot against the post.
Tottenham slip to eighth with 36 points.
When the Premier League resumed this week after a short winter interlude, Tottenham looked well-placed to challenge for a top-four finish as they have games in hand of their rivals.
Antonio Conte was undefeated in his first nine league games as Tottenham manager having taken charge in November, but the optimism that run induced is fading fast. It is the first time Conte has lost three league games in a row since his days managing Atalanta in November 2009.
Bruno Lage's rock solid Wolves, on the other hand, look capable of making a bid for European qualification and their travelling fans will be dreaming of a top-four spot. Conte made three changes to the side that lost to Southampton with Rodrigo Bentancur coming in for Pierre-Emile Hojbjerg and wings backs Matt Doherty and Ryan Sessegnon coming in for Emerson Royal and Sergio Reguilon.
But defensively Tottenham were a shambles again. Lloris initially did well to save a Ruben Neves shot but he then flimsily punched out Dendoncker's follow-up straight to Jimenez who volleyed the ball back into the net.
Son Heung-min wasted a one-on-one to level and almost immediately after Wolves doubled their lead.
Lloris played a terrible pass to Ben Davies whose clearance went straight to a Wolves player and when the ball was played to Daniel Podence his deflected shot hit the post and in the ensuing scramble Dendoncker bundled in.
Sessegnon was substituted before half time and replaced by Dejan Kulusevski but Spurs kept making mistakes. A poor pass by Winks ended with Podence forcing a fine save by Lloris.
