The Catalan saw his team fall to their neighbours to mark an historic personal low, but he is certain they can recover and start winning again.
Manchester City manager Pep Guardiola set his sights on other trophies as his team’s winless run continued with a loss to rivals United.
For the first time in the Spaniard’s career, his side have gone winless in six after losing 1-0 to Manchester United in the EFL Cup on Wednesday.
Guardiola remains upbeat over City’s chances of trophies this season, with the Premier League, Champions League and FA Cup still up for grabs.
“Yeah, it’s six games – not a good situation – but we are out of one competition, we have three still,” he said, via the club’s website.
“We are going to see. I happy with the players and we are going to try in the future.”
A second-half goal from Juan Mata was all that separated the city rivals at Old Trafford.
He said: “Aleix was outstanding – Pablo Maffeo as well, fighting with [Marcus] Rashford and [Paul] Pogba.
“We made a good performance, so there’s no regrets. We were still fighting until the last minute.
“We are a young team. Kelechi [Iheanacho] is 20, Leroy [Sane] 20, Pablo 19 – it is a good experience for them. Fernando played amazing and helped the other ones.”
