Ex-Leeds United defender Dominic Matteo is furious over taunting Millwall fans.
Matteo has branded Millwall thugs who mocked the memory of murdered Leeds fans Christopher Loftus and Kevin Speight "sick idiots".
Loftus and Speight were stabbed to death in Istanbul in 2,000 before the club's UEFA Cup semi-final with Galatasaray.
Yet only four days after the 11th anniversary of their slaying, Leeds supporters were subjected to throat-slitting gestures from Lions fans at the New Den eight days ago.
Matteo, 36, rapped: "They are a disgrace to their club and to football."
