Bodo/Glimt, perhaps surprisingly, dominated the opening half-hour and were rewarded with a penalty when Rodrigo Bentancur lunged into a terrible challenge in the area. Kasper Hogh, up front for the Norwegian team, took one of the worst penalties perhaps ever seen in Norway, as he managed to balloon his effort well over the bar - his second penalty miss in two games.
At half-time, Thomas Frank, astonishingly, made no changes, and Bodo had the lead within 10 minutes, as Jens Petter Hauge found his way into the penalty area, shimmied, and finished brilliantly beyond Guglielmo Vicario.
Spurs, though, thought they were level after 60 seconds; a free-kick from Pedro Porro on the left wing hit the post as it evaded all defenders, and Rodrigo Bentancur turned the ball home. However, a VAR review showed a foul by Micky van de Ven in the build-up, and the equaliser was ruled out.
Spurs' sense of injustice only deepened as Hauge added a second in the 66th minute, once again taking advantage of lax Spurs defending to work an opening and score from range.
Micky van de Ven pulled a goal back two minutes later with a very good header after a fine Pedro Porro cross, with Tottenham suddenly emboldened to chase a comeback, and Wilson Odobert hit the crossbar late on, as did Andreas Helmerson in a helter-skelter final period.
But it was Richarlison who found the net, as Bodo goalkeeper Nikita Khaikin could only parry Archie Gray's shot against the Brazilian, with the ball rolling over the line. A lengthy VAR check followed but the goal was allowed to stand.
