Man City: Manuel Pellegrini's problems & Sergio Aguero's blues

Manager Manuel Pellegrini says he is "not concerned" about his future, despite Manchester City's title defence being severely damaged at Crystal Palace.

A 2-1 defeat at Selhurst Park extended the champions' dismal form to four wins in 11 league games, a run which leaves them fourth, nine points behind leaders Chelsea.

Those costly slip-ups have seen City fall from second - behind Chelsea only on alphabetical order - and nine points clear of Manchester United to a point behind their local rivals ahead of Sunday's Manchester derby.
So should Pellegrini be worried about his future? And just what has gone wrong for his team?

"We are not thinking about Chelsea, or about the title. We are just trying to win our games," said Pellegrini after the defeat at Palace.
"All we can do is try to add the most amount of points we can in our seven games and we will see who is first, second, third and fourth."
City, champions in 2012 and 2014, have been undone by recent failings, including three consecutive away defeats in the league for the first time since 2011, when they finished third.
But Pellegrini does not fear the fate suffered by predecessor Roberto Mancini, who was sacked after failing to deliver silverware in 2013.
"I'm not concerned about my job. That is one thing I am never concerned with," said the 61-year-old.
"I never have fear about it, I do my work, I'm very happy. The team maybe have a difficult season but never worry about me."
