The England left back has set his sights on extending his loan at St James's Park, because he doesn't reckon Jose Mourinho will have him back next season.
He said: “First and foremost, I am playing for my future.
“I don't think I need a bigger motivation than that. I have settled in very well, I love the lads, and staff and the fans.
“It doesn't take a rocket scientist to work out that my days are numbered at Spurs. I am playing for my future – no bigger motivation.
“It is probably the first time in my career I have been in this situation – never have I been down to less than one year on my contract – so it's a new experience for me."
Rose says Mauricio Pochettino's departure at Spurs made life “difficult".
He added: It's not enjoyable that you are training and you know you're not going to be playing at the weekend.
“That's difficult. When my old manager lost his job, that was pretty much the end for me.
“I spent November not playing, December not playing, and then I joined here in January. It was very frustrating. I wasn't needed in the manager's plans at the moment in Tottenham."
