According to Willy Caballero, De Bruyne scoring his second go in a consecutive match will boost the performance of the midfielder.
De Bruyne was signed in a big money deal to City this season and scores against West Ham, before netting against Sunderland in the league cup.
And Caballero who started the match, has pointed out the significance of De Bruyne finding the net again.
“It is good for us,” he told City TV. “He [De Bruyne] is a new signing and it is good for him.
“It is also good for Kun, for Raheem, everyone. When they score, it is important because they will grow in confidence which is fantastic for us.
“We need to try to do the same in the league now, but we need to enjoy this game because when we lost the last two games, we were really unhappy with some mistakes and with other things.
“Now we have one or two days to enjoy this victory and then we will be thinking of the next game in the league. It is important for every player to get this result.”
League leaders City are back in action with a tough trip to face Tottenham at White Hart Lane on Saturday.
