City conceded a controversial penalty within 10 minutes against Fulham on Saturday, converted by Mladen Petric, when Pablo Zabaleta was judged to have fouled John Arne Riise – a decision which the striker branded as "wrong".

|9/2||Sergio Aguero is 9/2 to score the first goal in Man City v Borussia Dortmund with bet365
The Premier League champions went on to win 2-1 after Aguero scored just before half-time and Edin Dzeko netted a late winner, but referee Mark Halsey denied penalty appeals from Zabaleta and Carlos Tevez over the course of the match.
Aguero told reporters: "I try not to get involved with problems involving referees. There is a little bit of privilege with players who come from that country [England] but that is normal.
"We just play our game and the referee's job is to know who is tricking him and who is not.
"Here in England, there are almost as many foreign players as English players and it's not right that some have a privilege that others don't."
