Sunderland
The Magpies midfielder pulled no punches in his assessment of the 1-0 Premier League loss to the Black Cats.
The Newcastle United legend didn't hold back when giving his opinion on the match.
The midfielder moved to the Bundesliga side from Sunderland over the summer but has struggled for form in Germany.
The Black Cats were 1-0 victors in the Tyne-Wear derby thanks to Nick Woltemade's own goal.
