ROTTERDAM • Manchester City must not get carried away by their 4-0 win at Feyenoord but need to stay true to their attacking philosophy on the road if they are to do well in the Champions League, manager Pep Guardiola has said.

City equalled their biggest Champions League victory, offering a supreme display of firepower up front in their Group F opener on Wednesday.

Defender John Stones netted a brace while strikers Sergio Aguero and Gabriel Jesus both scored, taking the pair to seven goals in five outings in all competitions.

Guardiola said he was pleased with the result but stressed the need to guard against complacency.

"It's so important to win the first game and though nothing is achieved yet, it's a great start for us this evening," the Spaniard said.

"Last season we weren't able to win any games away in the Champions League and we spoke about that among the squad.

"It's important for us to see if we can go away from home with the same mentality we have at the Etihad. The same high press, attacking philosophy and not conceding on the counter-attack."

"The most important thing and what pleased me the most is the way in which we did it.

"We were aggressive, we had the legs to run on the side, especially on the right, and created the chances. Enough to win the game comfortably."

The 46-year-old also showered praise on Stones and the ever-impressive playmaker Kevin de Bruyne.

"John played well and while he scored two great goals, he did very well defensively, winning duels and doing what he had to do," the City manager said.

"That's what John needs to do to keep progressing over the next few years.

"Kevin is one of the best players I've seen in my life, in terms of being able to do absolutely everything.

"He's top, top quality. We are so proud and happy he's with us."

That was some compliment, given that Barcelona superstar Lionel Messi is among the footballers Guardiola has previously coached.

City, who are below leaders Manchester United on goal difference, return to Premier League action tomorrow with a trip to Watford.

Considering City's attacking prowess, Marco Silva's side will hardly fancy facing Guardiola's men then.
