Manchester City boss Pep Guardiola admits he'll be talking to his players about defending at corners after their 4-1 win at Stoke City.

The talking points from the fixture centred around the awarding of two penalties by referee Mike Dean for either side which may have been allowed to slide in previous campaigns.

City benefited in the first half when Ryan Shawcross' grab of Nicolas Otamendi's arm saw Dean put his whistle to his mouth and Raheem Sterling was adjudged to have impeded Shawcross at the same end in the second half.

"We have to be really careful," said Premier League newcomer Guardiola. "I like to defend zonal marking, not man-to-man, just attack the ball. It was a little bit strange but I think Mark Hughes can say the same.

"You will realise the manager of Manchester City is going to speak few, few times about the decisions of the referees. I'm not a guy who likes to complain."
