Manchester City boss Pep Guardiola feels that quality finishing has been the main factor behind his side's impressive start to the new season.

The Citizens have been unbeaten in all competitions this season, and as things stand, they sit top of the league table having scored 21 goals in their opening six games.

Ahead of his side's Champions League tie against Shakhtar Donetsk, Guardiola said: "My feeling is a lot of times we play in that way last season but in the boxes we were not good.

"On Saturday, they had two chances one with Loftus Cheek and last season that was a goal. We scored a goal in the last minute of the half and last season that did not happen once.

"We are more comfortable now. When we play at home we feel we are going to score goals. How many chances we create and concede is quite similar to last season. The stability can go down.

"We have to be careful and work in our habits and our fundamentals. Always we can do better and this is another test."
