David Moyes believes he could manage any team in the world and wants to prove it at West Ham.
Moyes appears to be instigating a revival at his new club, with Saturday's 3-0 victory at Stoke their third consecutive game without defeat.
Before then, Moyes' side had lost 2-1 at Manchester City before beating Chelsea and drawing against Arsenal at home.
They have climbed out of the relegation places and now sit 15th in the table ahead of Tuesday's Carabao Cup quarter-final away at Arsenal.
Like West Ham, Moyes admits he is also rebuilding his reputation after ill-fated spells in charge of Manchester United, Real Sociedad and Sunderland.
"I have to come here and show I can do it," said the Scot. "If you're any player you have to come and show what you can do. Your reputation doesn't stand for anything.
"You have to come here and try to get up and show you're capable of doing the job. I think I'm capable of doing the job at any club in the world so I'm sure I can do it at West Ham."
