Jenas said he was unimpressed with both sides, particularly the away side at Turf Moor, who slipped further off the pace in the battle for the top four.
He said: "You can't sugar coat it. For me it was the worst game of football I've seen all year. Spurs have set themselves such high standards, but they seem to get themselves into a way of playing, that they made so many errors."
Jenas went onto single out poor pieces of play from Kyle Walker, Eric Dier and Vlad Chiriches who all turned over possession unforced by the opposition.
Tottenham are not the only side to struggle at Turf Moor this season however, with Manchester United also being held to a dismal 0-0 draw earlier in 2014/15. Arsenal travel to Lancashire to take on the relegation battlers next week.
Spurs were also held in the FA Cup at the stadium earlier this year, before winning a replay 4-2 at White Hart Lane.
The verve shown in that performance was sorely lacking at the weekend, with Spurs perhaps mentally affected by their dreams of finishing in the top four fading.
An excellent season is at risk of petering out if they cannot lift their game over the coming weeks, and ensuring there is no repeat of Sunday's poor display is a big challenge for head coach Mauricio Pochettino to negotiate.
