Tottenham were only able to draw 1-1 with the Gunners back in November, but their performance in the tie was good.
The Lilywhites had the better of the the contest, but they were unable to make their dominance pay.
Harry Kane had fired Spurs into the lead, but Kieran Gibbs’ late equaliser stopped Mauricio Pochettino’s side claiming all three points.
Although that was a disappointing way for the match to end, from a Tottenham perspective, Jenas feels that the performance has helped Pochettino’s squad as the season has progressed.
"I think the derby at Emirates Stadium in November played a big part in Tottenham's development," Jenas said. "The game finished 1-1 but if you forgot the scoreline and just watched the game then Spurs pretty much destroyed Arsenal on every other level.
"Pochettino worked Arsene Wenger out like you would not believe and showed he knew exactly how to combat this Arsenal side.
"That was a huge moment for this Tottenham team as well as Pochettino and his backroom staff, and probably gave them the belief they can do something special this year."
Tottenham are Arsenal are due to meet again at White Hart Lane tomorrow, in what is one of the biggest North London derbies of all time.
If Spurs are to beat the Gunners they will move to the top of the Premier League, and put six points between them and their near neighbours.
If Arsenal are to be victorious, however, then Arsene Wenger’s men would move into the thick of the title fight - and close the gap on Leicester City to just three points.
