Spurs slaughtered the Scandinavians 5-1 on aggregate in May under then manager Ange Postecoglou, who made light work of the side even when they jetted off to play in the Arctic Circle for the away leg.
Tottenham now travel to the Norwegian side for their second league phase match after an 1-0 opening victory over Villarreal as they enter the clash on a five-game unbeaten sequence in all tournaments.
However, Sakariassen has warned Tottenham that his side has only improved and that their loss last season has boosted their performances.
"Tottenham actually played a really good game here at Aspmyra against us.
"Really well organised, loyal to the plan and of course they have really world-class players. If they perform that well in their task, it is always going to be tough for us.
"For us it was a lot of learning. The reflection for us after the game is was there enough level on the physical side?
"So, actually that brought something to the table for us that we are grateful to have the knowledge about.
"It means we have since then changed and worked in a slightly better and more reflective way to see if we can realise the potential in the physical side of our players.
"I think that made us stronger and hopefully we will see that when we see them again that we actually moved up a step. That will be interesting."
Tottenham have won all six of their previous matches against sides from the Scandinavian country, and on paper it looks like an easy affair. However, if Bodo/Glimt have improved, then the North London side could be in for a shock as their European campaign resumes.
