Alvaro Negredo scored a hat trick and Sergio Aguero struck twice as Manchester City reached the Champions League knockout stages with a convincing 5-2 defeat of CSKA Moscow.

The result was never in doubt after Aguero scored a penalty in the third minute at the Etihad Stadium, and the in-form hosts were 3-0 up after half an hour.

Seydou Doumbia twice soured the scoreline with a goal on the stroke of half-time and a late penalty, but Manuel Pellegrini's men were not threatened and secured qualification for the first time with two games to spare.

Aguero's second after 20 minutes was his 13th of the season and Negredo then put City in complete control. He added his second soon after the break and completed his treble in the final minute. Following exits at the group stages in each of the past two seasons the result represented the next major step forward in City's development.

After the meeting between the two clubs in the Russian capital a fortnight ago was soured by racist chanting aimed at Yaya Toure, the crowd, who chanted the midfielder's name throughout, were in focus. Stewards acted quickly to remove a banner unfurled by City fans reading, 'Free Pussy Riot', referring to the members of the imprisoned members of the Russian protest band, and midway through the first half police and stewards also moved in among the CSKA supporters after what may have been a minor disturance and a smoke bomb was later let off.

Toure paid tribute after the match. "It's amazing," he said. "I think it's deserved by the club. We go through to the second round for the first time, it's unbelievable. I thought we played amazingly well today and we have to say thank you to the fans as well. They showed to the fans of CSKA how supportive our fans are."
