Manchester City suffered a surprise exit from the League Cup as Aston Villa clinched a 4-2 third round win at Eastlands, while Chelsea welcomed back controversial captain John Terry with a 6-0 rout of Wolves.
City manager Roberto Mancini made 11 changes from the side held to a 1-1 draw by Arsenal on Sunday and the Premier League champions weren't able to win with their stand-ins.
Italian striker Mario Balotelli fired City ahead in the 27th minute, but Villa equalised in the 59th minute when their former midfielder Gareth Barry deflected the ball into his own net.
City regained the lead when Aleksandar Kolarov clipped a free-kick past Shay Given in the 64th minute, but Gabriel Agbonlahor restored parity six minutes later.
And in the sixth minute of extra-time, Agbonlahor fired in a shot that City goalkeeper Costel Pantilimon couldn't hold and Charles N'Zogbia was on hand to slot home before Agbonalahor completed the upset with seven minutes remaining.
At Stamford Bridge, Terry skippered Chelsea just hours after appearing at the second day of the FA disciplinary hearing into charges he racially abused QPR defender Anton Ferdinand last October.
It took Chelsea just four minutes to welcome Terry back as his central defensive partner Gary Cahill headed home from Juan Mata's free-kick.
