Made his Sunderland debut in a 2-0 win at home to Watford before grabbing his first goal with the winner against Sheffield Wednesday a month later.
Became an important player as Sunderland achieved two consecutive seventh place finishes in the Premiership.
But, as Sunderland's form slumped in the 2001/02 season, Schwarz became one of the casualties. Fell out of favour and at the end of the season was told he was free to find a new club.
Seems unlikely he will add many more games to his 74 appearances for Sunderland. Has scored three goals for the Black Cats.
