Middlesbrough ran riot against a beleaguered Manchester City side.
City's problems began when Richard Dunne saw red for fouling Tuncay and Stewart Downing scored from the spot.
Afonso Alves drilled home, then Downing hooked into the net and Alves ran clear to make it 4-0 before Adam Johnson scored with a deflected effort.
Fabio Rochemback's fierce free-kick was followed by Jeremie Aliadiere's low shot and, although Elano replied, Alves completed his hat-trick to make it 8-1.
If, as is widely expected, this game proves to be Sven-Goran Eriksson's final game in charge of City then it was a miserable end to his reign at Eastlands.
And if City owner Thaksin Shinawatra was still unsure about the Swede's future before kick-off, this defeat could well have made up his mind for him.
City were torn apart by Boro who, without some excellent saves from visiting keeper Andreas Isaksson, would have reached double figures at a canter.
