"Only some inspired goalkeeping from Maarten Stekelenburg stopped them beating Everton on Saturday and Ronald Koeman admitted City were the best team he has faced in his entire managerial career".
City have been awarded eight penalties this season and have missed four, an appalling record that can not be ignored.
Aguero was on the pitch for 14 minutes when he earned his own penalty, with Jagielka again the Everton player committing the foul.
"I don't have time to practice everything I want to practice".
"You can practise penalties in training, but in training, no one (a crowd) is there".
Pep Guardiola conceded Manchester City's confidence may be cause for concern amid a stuttering run of form as they prepare to face Barcelona in the Champions League.
It is far too early in the season to suggest that Guardiola is becoming desperate, but when, nearly laughably, he sent on Vincent Kompany as a striker for the last few minutes it could only be interpreted as a sign of frustration.
Louis Enrique (Barcelona): "I've still not spoken with Pep but this was the ideal way to go into the match against City, winning against Depor".
"Of course, they are one of the best teams in the world so we need to compete".
Manchester City manager Pep Guardiola is not planning to sign any players during the January transfer window, according to the Mirror.
His players gave him all three and Koeman recognised this by praising the team, "A big compliment to the team because we fight." he said.
However, once the game started it it became quite evident it was three at the back with Otamendi - Stones - Clichy; Fernandinho and Gundogan in midfield with David Silva and Kevin De Bruyne as the primary playmakers just ahead of them.
"They have three unbelievable players - Lionel Messi, Luis Suarez and Neymar - up front".
"We did absolutely everything", Guardiola said, after seeing his team have 72 per cent possession and 19 shots on goal.
De Bruyne replaced Aguero as penalty-taker and his kick was a nice height for Stekelenburg, who parried the ball away diving to his left.
"He will be hard to stop, I know that from experience".
"I hear a lot of times about the intensity in the Premier League when none of you have been in La Liga or the Bundesliga to know how intense it is", he said.
