"Harry [Redknapp, Tottenham manager] knows what I am like and the type of personality I am. I just love playing football and he fully respects that."
Keane, who will lead his country in an end-of-season friendly against World Cup finalists Paraguay on Tuesday, added: "I love to play football and I am not one of those people like to sit on the bench and pick up the money and be happy with it."
He has also hailed Tottenham's "massive achievement" of breaking into the top four of the Premier League and so earning a shot at the Champions League.
Keane cost Tottenham £12m when he returned from Liverpool six months after the north Londoners sold him to the Anfield club for £19m in July 2008.
The striker, who joined Tottenham from Leeds for £7m in 2002, will face competition for a starting place from Peter Crouch, Jermain Defoe and Roman Pavlyuchenko next season.
