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.
Guardiola said: “Kevin is one of the best players I’ve ever seen in my life in terms of he can make absolutely everything.
“He’s a top, top quality player. We are so proud and so happy he’s with us.”
City are now already in a strong position in Group F ahead of back-to-back home games against Shakhtar Donetsk and Napoli.
Asked if it was the perfect start, Guardiola said: “Of course. I said yesterday it’s important to play good.
“I’m proud that we have scored nine goals in two games when we’ve had a lot of problems in that (area). Of course to score two early goals was so important.
“Three points are very important to start the group stage. Last season we were not able to win one game away. That’s why if you want to make a step forward you have to do this.”
