Tottenham boss Ange Postecoglou says big changes will be needed this summer.
Spurs have been hit by major form slump over the past month.
Postecoglou said: "We need change, change has to happen.
"You can't want to alter your course, and quite dramatically for this club because we went down a certain direction and now we're pivoting to a whole different direction, and expect the same people are going to be on that…It's just not going to happen, so…
"We've had two windows and we've had some development of players, for sure, but when I say we've still got a long way to go, that's what I'm talking about. We can't be there yet because it's impossible to say you're going to have drastic change and yet expect everyone to be on that journey. It's not for the want of trying..it's just that we're going to play a certain way, we're going to train a certain way and we're going to have a certain mindset, and that's not for everyone.
"And the same way, whether it's Liverpool or Arsenal, if you look at the beginning of their journeys, by the time they win the competition or have success, the team's almost unrecognisable. That's the reality, if you change. If you're staying on the same course, of course, or a similar course…but we've done a major pivot here, so that definitely is the case, yeah."
