Sunderland midfielder Lee Cattermole has insisted that "things have to change" after his side succumbed to their second defeat of the season with a 3-1 home loss at the hands of newly-promoted Norwich City.
A late goal from Duncan Watmore three minutes from time was the only consolation for the Black Cats, who sit bottom of the Premier League table.
"We are conceding goals out of nothing and it is very disappointing. Things have to change quick and we have a lot of hard work ahead," Cattermole told BBC Sport.
"It is up to the players, manager and staff to kick on and fight. We have to look to improve."
Sunderland are next in action when they host Swansea City next Saturday.
