Aguero missed the final few weeks of the campaign with a knee injury, but he nevertheless managed to reach 30 goals for the season in all competitions.

"I always had problems in that area and now I feel different, now I can flex it and it's a great relief".
"I spoke with the Manchester City doctors this season and said, "we are going to wait because we have the Champions League".
"Pep supported me a lot".
