Opposing manager Antonio Conte meanwhile praised De Bruyne as a "complete player", as Guardiola also expressed satisfaction at how complete his team's performance was, how they beat Chelsea by taking the game to champions in their own stadium.
A stunning Kevin De Bruyne strike mid-way through the second half helped secure a 1 - 0 win for Manchester City against Chelsea at Stamford Bridge. "Manchester City had chances and they took them", he said.
Manchester City: Ederson: 7, Kyle Walker: 8, John Stones: 6, Nicolas Otamendi: 6, Fabian Delph: 7, Fernandinho: 7, Kevin De Bruyne: 9, Leroy Sane: 6, David Silva: 7, Raheem Sterling: 8, abriel Jesus: 6.
The visitors' pressure began to grow shortly afterwards, though, with Silva and Jesus both coming close in quick succession before the breakthrough finally arrived in some style.
Guardiola, who signed De Bruyne two years ago after watching him play in the Bundesliga, publicly praised the former Chelsea player earlier this month for his quality, commitment and intelligence.
The English title-holders were magnificent in overcoming Atleti 2-1 in the Champions League on Wednesday but after the match Conte complained that City had been granted extra rest ahead of a crunch domestic clash - Pep Guardiola's men having beaten Shakhtar Donetsk 2-0 on Tuesday.
Antonio Conte's men were dealt a huge blow halfway through the first forty-five as Alvaro Morata was forced to go off injured.
"We have to pay attention tomorrow, as it won't be easy against City".
As a result, City have run riot not in recent weeks as they have scored goals at an incredible rate. "This season they have more problems because they have to play every three days".
"He said to me 'coach I prefer to stop myself otherwise I risk a bad injury.' I don't know". His first start of the season went amazingly well and he was Chelsea's best player on the pitch.
De Bruyne was dumped by the Blues after hardly getting a chance to prove himself before he was allowed to leave for Wolfsburg.
