Tottenham produced a rotten performance in front of their home fans on Sunday as James Morrison's header earned West Brom their first league victory of the season.
Under Mauricio Pochettino, Spurs have started pretty well but after a tepid display in Belgrade on Thursday night, a much-changed side performed even worse in front of the White Hart Lane crowd.
From the first minute they were outfought by a resolute and organised West Brom side who thoroughly deserved the three points.
Younes Kaboul and Vlad Chiriches gave early glimpses of what was to come when they dithered in possession to give West Brom strikers Saido Berahino and Stephane Sessegnon early sniffs of goal and after giving away numerous corners, Spurs were extremely lucky not to give away a penalty when the ball struck Emmanuel Adebayor's outstretched hand.
At the back, the Baggies were holding Spurs at bay with ease, with Joleon Lescott in particular excelling.
Once or twice Tottenham threatened to get in behind the West Brom defence but Alan Irvine's men defended from front to back and the home side only had one effort on target in the whole game.
Despite dominating possession, Spurs struggled to create anything of note. Adebayor was isolated, Nacer Chadli and Christian Eriksen anonymous and a central midfield pairing of Etienne Capoue and Mousa Dembele was far too defensive and reticent to break forward from their comfort zone.
West Brom inevitably took the lead when, with 15 minutes to go, Chris Brunt delivered a corner and James Morrison managed to lose his marker and head in from seven yards.
So chaotic was the Spurs defending it was hard to tell who was supposed to be his marker, but my finger points at the inept Paulinho.
More defensive lapses from Chiriches and Danny Rose allowed West Brom further sighters of goal but Hugo Lloris did at least deliver an acceptable performance.
No Plan B
With 15 minutes left to play and having already switched to a two striker formation, Spurs fans may have expected to see their side throw the kitchen sink at West Brom's defence but it was less kitchen sink and more damp sponge as Lescott and company easily kept out a Tottenham team who were insistent on attacking through a ten-yard strip down the middle of the pitch.
Tottenham earned several corners and free-kicks late on but Eriksen failed to deliver a threatening ball - adding to his poor start to the season - and West Brom hung on with room to spare to seal their first win of the league season.
