Norwich City owner Mark Attanasio has set a target of having a competitive Premier League team within five years.
The American's Norfolk FB Holdings Group now owns an 85% stake in the club, who are currently 14th in the Championship.
City were relegated after a single season following their last three promotions - in 2015, 2019 and 2021 - and Attanasio said he would feel he had failed if they do not achieve top-flight football again within five years.
"You need a complete buy-in from everybody top to bottom to do this. An owner can set the tone but everybody from the owner down to the assistant coach in the academy has to be rowing in the same direction for this to work," he told BBC Look East.
