The 27-year-old struggled to get into the Spurs team earlier this year because of a groin problem and was forced to dose himself up on painkiller.
Jenas eventually had an op and is now keen to retain his place for the Champions League clash with FC Twente.
He said: “There has been constant rumours about me leaving but I just wanted to be settled and part of the Tottenham team again.
“At one time I felt I’d have to leave because all I wanted to do was play football and I wasn’t getting games here.
“But despite the offers that came in, they were not worth leaving for.
“This is the best I’ve felt since a few years ago.
“I was carrying a groin injury for at least a year – maybe because I was under a bit of pressure in my own position and I was trying to just delay, delay, delay the surgery. But I had to do it in the end.
“I was taking painkillers to try to get through it and in the end it just broke down.
“There’s Champions League football now and I’ll be fighting tooth and nail to get a regular starting place.”
