Eriksen had been in negotiations with Spurs since September last year, and has now agreed a four-year deal worth about £75,000 per week to stay at White Hart Lane.
Had he not signed, Eriksen would have entered the final year of his contract at start of next season.
It was suggested that he had asked for as much as £150,000-a-week to commit to Spurs again, a figure Tottenham are highly unlikely to have paid.
"Since I came in the last two years we have been going forwards, are taking steps upwards and I want to be a part of it.
"I see a great future, it is going only one way at the moment. I think it is a very good group of people and players who can connect with each other and a group of staff who connect with the players.
"We have an idea of where we want to end and hopefully we will achieve that."
