Manchester City striker Sergio Aguero has singled out his team's key players.
Kun has hailed the quality of City's squad this season.
"It is always vital in any team to be able to rely on your key players on the field.
"Players like Joe Hart - he is having a great time of things at the moment and that is helping us a lot. Vincent Company in defense - what can you say? He is quite simply one of the world's best defenders.
"Then you get a balance by the guys in the middle of the park, people like Sammi, Silva and Yaya ..and it's fundamental with these key players you can enjoy a balance they provide to the entire 11."
