Gary Neville has hit out at David Luiz after the Brazilian's disastrous 26-minute cameo performance at the Etihad Stadium ended with him being sent off.
The Arsenal centre-back - who came on for the injured Pablo Mari after 24 minutes - was at fault for Raheem Sterling's opener after failing to deal with a cross from Kevin De Bruyne.
The 33-year-old was then shown a straight red card five minutes into the second half by Anthony Taylor after hauling down Riyad Mahrez in the box, with De Bruyne converting the spot kick to put City two goals to the good.
