Allardyce has set his sights on a quick return to the Premier League after being confirmed as the new manager of West Ham.
The former Bolton, Newcastle and Blackburn boss has agreed a two-year contract at Upton Park.
Allardyce said: "It is an honour to be the new manager of West Ham United. It is a fantastic club with a great tradition and loyal supporters who deserve to be in the Premier League.
"I can't wait to begin pre-season training as I am determined to get this club back where it belongs.
"I wouldn't have taken this job if I didn't think we could bounce straight back into the Premier League. More than that, I wouldn't have contemplated the job if I didn't think there was the opportunity to build something substantial at West Ham."
