A "disgraceful" Sunderland side need "major surgery" if they are to return to the Premier League, says former England captain Alan Shearer.
The Black Cats, who were relegated with four games to go, were beaten 2-0 at home by Swansea on Saturday.
Former Newcastle striker Shearer said the hosts' display was "pathetic" and fans should demand a refund.
"There is no way that team will get back up into the Premier League," he said on the BBC's Match of the Day.
Manager David Moyes has said he will remain in charge despite relegation, but striker Jermain Defoe looks set to leave.
