The Catalan was pleased with the overall performance from his players, but says while the football was scrappy in the first half, the second was ‘outstanding’.
“It is important to win this trophy because our supporters are so happy,” said Pep.
“I’m happy for our fans, for my staff, for the players and for Sheikh Mansour and our Chairman Khaldoon Al-Mubarak.”
Asked why he stayed on the pitch for the trophy lift the boss said: “Because it’s nicer to see it from the pitch – you get to see everything much better.
“The first half was not good – too many mistakes with simple passes – but the second half we played with more courage, more personality. That is why we were outstanding after the break.
“It was so important we won this after going out of the FA Cup. It’s a pity because we played 45 minutes against Wigan with 10 against 11 and we played good, but unfortunately couldn’t go through.
“Now we have to focus absolutely on the Premier League and trying to win the games we need to win the title and try and progress to the Champions League quarter-final.
“This win is not for me, it’s for Manchester City."
Guardiola gave an update on Fernandinho after the midfielder limped out of the match and revealed the Brazilian midfielder could be set for a spell on the sidelines.
The boss added: "The next games I think he will be out. We will see on Monday the extent of the injury but it’s a big, big loss for us."
