"He's 24 and he's the captain of the side. Sometimes he needs to keep his discipline better because over the course of the year I expect he'll pick up a couple of silly bookings.

Cattermole has made 69 league appearances since moving to the Stadium of Light from Wigan in 2009 and established himself as one of the club's key players.
Sunderland host Liverpool on September 15 with both sides looking for their first league victory of the season.
