Pablo Zabaleta admits the inquest has begun at Manchester City over their season collapse.
Manuel Pellegrini's men were top of the table on New Year's Day but have slumped to fourth and now face a battle to get into the Champions League next season.
Zabaleta said: "It is time to analyse what we are doing wrong and try to improve for the next few games.
"There are still 18 points to play for and we must be honest with ourselves and start to push hard, play better and win games, so we can get in the top four."
