Aston Villa owner Randy Lerner has announced that the Premier League club is being put up for sale.
The American assumed control of Villa in 2006 after a £62.6m takeover was agreed with the club's board.
"I owe it to Villa to move on, and look for fresh, invigorated leadership, if in my heart I feel I can no longer do the job," he said on Monday.
Villa finished the 2013-14 season in 15th position, five points above the relegation zone.
Lerner had said last month that he would address speculation regarding his own future at the club in the summer.
Villa's Premier League status was only secured with victory over Hull City on 3 May and the future of manager Paul Lambert remains uncertain.
