Former Sunderland chairman Niall Quinn says new manager David Moyes needs to buy a new striker.
Quinn, who was chairman of the club between 2006 and 2011, believes Moyes' first task at the Stadium of Light is to find support for Defoe.
"Relying on Jermain Defoe to keep Sunderland in the league or indeed push up the league, I don't think they can go through the year with just that," Quinn told Sky Sports News HQ.
"I think it would be encouraging if Sunderland were to sign another proven goalscorer."
