Sunderland midfielder Steed Malbranque has rapped teammates after their slow start to the season.
Midfielder Lee Cattermole saw red in the opening-day draw with Birmingham as the Black Cats blew a 2-0 lead.
Team-mate Steed Malbranque admitted: "We need to be a bit more intelligent.
"We need to learn that, after a yellow card, you can't risk a bad challenge five minutes later."
