Jamie Carragher has urged Tottenham not to sack Ange Postecoglou, but admits "certain things" need to change.
Tottenham have picked up just one win in their last seven games across all competitions, a brilliant 4-0 victory over Premier League champions Manchester City, but Postecoglou has come under fire after Spurs' latest defeat to Chelsea on Sunday.
However, Carragher has defended the Tottenham boss, despite claiming they will never "go on and win something" if Postecoglou does not make some changes. "I love Ange Postecoglou since he's come into the Premier League, in terms of the football they play," Carragher said on Sky Sports' Monday Night Football.
"It's exciting. They are the most entertaining team in the last 18 months that I've seen. I know a lot of supporters wanted their Tottenham back and in a way, he has given them their Tottenham back.
"They're exciting to watch. They're almost everyone's second team. But you don't ever think they'll go on and win something. Now, is that a little unfair of me to say because do Tottenham ever win anything? That's the point.
"Is this a team set up to win big things? I said yesterday, if certain things don't change then he'll be out of a job. I don't want him to be. I enjoy watching them play, a lot more than previous managers.
"It has to be better than that for Spurs. No one's expecting Spurs to win the title but if he doesn't bow to certain things we're talking about, then eventually... That's what happens. You go to Man City and you win a game 4-0.
"But then you'll get battered by another team. You don't ever get that consistency you need to be a Champions League club. That's what Tottenham want." Despite Tottenham's recent poor form, Carragher believes Spurs' biggest problem lies in the transfer market and has suggested that chairman Daniel Levy should step down.
"It's probably time for somebody else to come in because to not win a trophy in that period of time with the managers they have had, they've never really gone out of their way in the transfer market,' Carragher added.
"They've spent decent money without blowing other teams out of the water, their wage bill is always one of the smallest and you're never going to get the best players. So it might be time for Daniel Levy - who I've been a supporter of because you look at the actual work that he's done - but now that works done in terms of a stadium and a training ground, someone else needs to be in charge of this football club."
