Speaking ahead of his side's upcoming clash with Newcastle United, Pochettino confirmed that Janssen will be given one of the free spaces in Tottenham's Premier League squad. "We always believe in ourselves", he told Sky Sports.
Pochettino can see parallels as his Spurs side aim to overtake second-placed Manchester City on Saturday and close in on leaders Liverpool, pointing out the difference in resources after Tottenham ended a second successive transfer window without a single signing.
"I want to win for my CV, I want to win for my fans, for my players, for my family too", he said.
"Of course I wanted to strengthen the squad, but if we can not and we can not sign then I need to stick with the project of the club".
"I think Tottenham are at a point now where winning the FA Cup or the League Cup is much more important than being in the Champions League the year after".

I feel very good at the moment, I feel in form, I can run a lot and recover the ball and I feel good when I have it on my feet. The interim boss said: "I enjoyed Marcus' finish". "I will always advise the club, especially if they ask me".
"We have a positive mentality and we're showing a great mentality".
In contrast to Redknapp's words, Pochettino has expressed his frustration at not being able to add to his squad in January, claiming he did indeed want to make some signings.
"You can be a victor but if you don't have the tools to win, it's hard", Pochettino said at his pre-match press conference ahead of Tottenham's match against Newcastle United on Saturday. When he's on the pitch he always gives 100 percent with or without the ball. "It is a fantastic result for us to be in a fantastic position in the table and I can feel very happy and very proud".
However, the visitors had chances of their own to spring another surprise as Salomon Rondon hit the post and Hugo Lloris made a flying save from Ayoze Perez early in the second-half.
"The goal we could avoid and is something we were not expecting".
