Manchester City defender Martin Demichelis admits they must improve their defending at set-pieces.
City boss Manuel Pellegrini has hinted the Blues will be working hard at both defending and attacking set-pieces during their week's training camp in Abu Dhabi.
Demichelis said: "We know we have been conceding from penalties and set-pieces lately, but it is the thing we work on most on the training ground.
"We have to check out the mistakes once again and, hopefully, it won't happen again."
