Spurs face Basle tonight in the Europa League.
Parker said: "There probably aren't many (former winners) in the squad. I know for a fact every one of us in that changing room wants to go on and be successful and try and win something.
"Winning becomes a habit - you know you're going out and you can grind out results. When I was at Chelsea we used to grind out results when we weren't playing well. There's a know-how and that's probably where we need to get to. I think we're close to it."
