USA coach Jurgen Klinsmann is urging Tottenham chairman Daniel Levy to stick with Mauricio Pochettino long-term.
Widely-criticised chairman Daniel Levy has made Pochettino his third manager in under a year after Andre Villas-Boas and predecessor Tim Sherwood and Klinsmann urged him to exercise more patience with the 42-year-old.
"If you have only four or six months you're not making that big difference. Arsene Wenger is (at Arsenal) for many years so you can only make that difference over a long period of time which he did.
"Look at Alex Ferguson, how much did he win in the first three or four years? Not much. But then he brought the consistency to what Manchester United is today. That's the way it works."
