Walker praises the job Pochettino has done, and talks up his man management.
There have been suggestions that other clubs are interested in the services of the Argentine, as he has overseen some fairly rapid progression at White Hart Lane during his two seasons at the club.
He has guided them to a League Cup final, and this season they are in the thick of the title race, and look certain to qualify for next season's Champions League.
Walker told the Evening Standard: “It is vital. We’ve built a foundation now. We don’t need managers coming and going. He did well at Southampton and he’s come here and done well so he’s proved he’s a very good manager.
“His door is always open. You hear players saying that a lot about various managers but with him, it really is true. Whenever you want to talk to him about something, you can knock on his door, even if it’s not about football.
“If you’re having any kind of problems, you can knock on his door, sit, talk, and it just takes the weight off your shoulders, knowing he backs you and knows how you’re feeling. He is a very good man-manager.”
The Mirror reported yesterday that Spurs seem to be taking steps to secure the future of their manager by offering him a new contract, even though he has three and a half years left on his existing deal. If they can tie him down to a new deal then that will be an excellent move for the club, especially given the progress they have made under Pochettino so far.
The fact that members of the squad are talking the manager up in public should ensure that any discussions that take place are concluded positively and quickly.
