Harry Redknapp's side are now up to 11th in the table after a six-match unbeaten run which has seen them claim 14 points from a possible 18.
This run means they can now think about European qualification via the league as they are just three points behind seventh-placed Wigan in the race to land a place in next season's Europa League.
Jenas told the club's official website: "I think we're showing the quality we have within the squad at the moment, and we really should be in the top half with the players we have.
Quick"We're quick on the break, we've got pace everywhere, and everyone's looking to get forward and get goals at the moment.
"The mood is very high at the moment, and what better way to go into a break than by beating a top side like Chelsea.
"It's been a fantastic few weeks, and since the Carling Cup Final, I don't think you can praise the lads enough for the attitude towards every game and training session."
After the international break, Spurs travel to Blackburn on 4th April - in a game being shown live on Sky Sports 1 and HD1 - and Jenas wants to continue the good run at Ewood Park.
Habit"We've got the bit between our teeth and want to keep going, because it's a great feeling when you're winning and a habit we want to continue," he said.
"Last year our form tailed off towards the end of the season, and perhaps that did affect us a bit this season.
"But we've got a top squad and all we want to do is win games, so the mentality is good at the moment."
