Pep Guardiola praised John Stones and Kevin De Bruyne after Manchester City opened their Champions League campaign with an emphatic 4-0 win at Feyenoord.
Defender Stones headed two goals, including the opener in the second minute, while playmaker De Bruyne delivered another passing masterclass in an outstanding team performance at De Kuip.
Strike pair Sergio Aguero and Gabriel Jesus were also on target as City ran the Dutch champions ragged.

Manager Guardiola said of Stones: 'There is no doubt about his quality. His two goals were so important.
'John knows what is the gap and where he has to improve, defending the duels, but he's so young and he is able to achieve.
'When he does, he will become an exceptional central defender.'
De Bruyne, who also impressed in last week's 5-0 thrashing of Liverpool, was the leading light of a brilliant midfield.
