Pep Guardiola has urged Manchester City's free-scoring forwards to stay hungry for goals and says there are many ways in which the Premier League leaders can improve despite their ominous early-season form.

City, who lead Manchester United on goal difference, have been in impressive form in recent weeks, thumping Liverpool, Watford and Crystal Palace in their past three Premier League games by an aggregate score of 16-0.

Combined with a 4-0 thrashing of Feyenoord in the Champions League, and a more modest 2-1 victory over West Brom in the League Cup, City's momentum since the last international break has been formidable.

The results have pleased manager Guardiola but he is still not satisfied, as shown in the visible signs of frustration he displayed during a scoreless opening 44 minutes of Saturday's 5-0 defeat of Palace.
