Anthony Gordon says Newcastle United's defeat by rivals Sunderland is "not good enough" because the Black Cats are "not very good" compared to the Magpies.
Sunderland completed a league double over their north-east rivals on Sunday with a 2-1 win at St James' Park, having beaten the Magpies 1-0 in the reverse fixture.
The defeat means the Tyneside club have failed to beat Sunderland in any of their past 11 league meetings - the longest winless run for either club in the fixture's history.
