Baggies boss Sam Allardyce struck a familiar tune after watching his side lose 2-0 at Spurs.
Albion were again much changed from the side which lost 2-1 at Sheffield United in the week with Ainsley Maitland-Niles, Lee Peltier, Conor Gallagher, Romaine Sawyers and Karlan Grant all recalled.
The Baggies held firm until half time and were unlucky not to take the lead when Mbaye Diagne saw his header saved on the goalline on the stroke of half time.
But Albion were undone nine minutes after the break when Harry Kane was left unmarked in the box to slide a shot past Sam Johnstone. Heung-Min Son then scored Spurs' second when the hosts broke quickly.
Speaking to BBC Sport, Sam Allardyce said: "The downside is letting the goals in after containing them in the first half. Seeing Harry Kane in our box unmarked. That lapse at this level just can't happen. We should be stopping that at source.
"Then we let them go from their box to our box without putting a mark on anyone. We scored, it got disallowed, we scored again and that was disallowed but at least we scored two 'goals' here. If we get the right service in the box we've got a man who can score.
"Until we shut the back door, better life is going to be difficult for us. This is it now, the window is shut, we've got what we've got. We've got to start winning games and we won't do that by keeping on losing. We need an undefeated run with more wins than draws in it."
