Norwich's joint majority shareholders Delia Smith and Michael Wynn Jones have hit out at their side's display in the 3-1 defeat at Plymouth on Saturday.
In a statement, Smith and her husband Wynn Jones said they were "deeply disappointed" by the lack of passion.
The statement adds: "We wish to apologise particularly to the 776 loyal supporters who undertook the long and arduous journey to Plymouth."
The pair go on to say to the Norwich City supporters: "You deserve more."
Smith and Wynn Jones said they remained committed to achieving success at the club.
"To that end, we expect this situation to be rectified at our next home game on Sunday and at our next away game," the statement reads.
"We rely on our manager and squad to do this not only on behalf of our supporters but for the long-term future of the club."
