The 19-year-old midfielder was named man of the match after playing a starring role in City's 2-1 defeat of Aston Villa at Wembley on Sunday.
"At the end, we suffered a little bit but I think we had enough chances to score more goals, but we are happy for the team".
Phil Foden, who was excellent for City, echoed his team-mate's sentiments regarding the challenge posed by relegation-threatened Villa, and rejoiced in his own input, which included an assist for Sergio Aguero's opener.
This season City could win the treble, with the FA Cup and Champions League still available, but Guardiola's absurdly high standards mean that it will not be considered a success in his mind because they will nearly certainly miss out on the Premier League title.
"The most attractive trophy is the Premier League and that is not going to happen, because we weren't consistent enough", he told reporters at Wembley.
A lofted ball to the far post by Spain worldwide Rodri was headed back across goal by Phil Foden for Aguero to volley into the turf past goalkeeper Orjan Nyland and into the net.
Instead, City doubled their lead as Gundogan's corner was met with a powerful downward header from Rodrigo.

However, City failed to turn their dominance into more goals as Rodrigo was denied by a fine save by Nyland from another corner before Aguero then fired into the side-netting to give Villa hope for the last 10 minutes.
Prince William, a Villa fan, slumped into his seat. Anwar El Ghazi took advantage and crossed for Samatta to send a powerful header past Claudio Bravo.
Mbwana Samatta's goal just before half-time helped restore Villa's pride and some credibility for the competition.
But Bravo did well to push Bjorn Engels' header onto the post in the 88th minute and ensure the 60th League Cup final was a victorious one for City.
Following a barren first season in charge, Guardiola has led City to two Premier League titles, three League Cups, an FA Cup and two Community Shields.
"We are always thinking of the next one", Bravo said. The Chile goalkeeper has not been offered a new deal by City because he has indicated he wants to play regularly.
He has however made four Champions League appearances, and has managed two goals; both of which were against Dinamo Zagreb.
That should have revved up Villa for a rousing second-half display but in truth they never really got going until it was too late. "You can't hide away from the fact that we're in the bottom three now with the results that happened yesterday".
