Tim Sherwood says the uncertainty surrounding his future as Tottenham Hotspur manager is similar to that of a school supply teacher.
Sherwood has been forced to deal with constant speculation over his job security since taking charge in December, with the likes of Frank de Boer, Louis Van Gaal and Mauricio Pocchettino all linked to the role.
"People will always judge on what I've come in and done," he said.
"You're absolutely right, it's imperative to have a pre-season and bed your ideas in. And also I'm doing it with a lot of uncertainty around my future.
"If you have a supply teacher who comes into your school, sometimes they're not treated with the respect that a headmaster is."
