Despite a lack for first-team opportunities, the midfielder hopes to earn a place in Slaven Bilic's Croatia squad for Euro 2012.
"I still believe my future is here," he said. "I know the next few months I want to stay, get in shape and hopefully have a good Euro 2012.
"The club have been great with me since I came. If I don't play here I still hope to be in good shape for the Euros.
"I would hope to prove myself in the friendlies before the tournament. That's why I'm staying."
The 27-year-old joined Spurs from Portsmouth in 2009 for £2.5m.
