Manchester City manager, Pep Guardiola, has urged his players to improve despite their 3-0 victory over Manchester United in the Premier League on Sunday.
The former champions secured only their second win of the campaign against United at the Etihad.
After opening the season with a 4-0 win over Wolves, City suffered back-to-back defeats against Tottenham and Brighton.
Ahead of their Champions League clash with Napoli, Guardiola has called for greater spirit within his squad.
He told Sky Sports: “It’s a privilege to bring joy and some moments of happiness because I know how much the derby means.
“It is just one game. We did many good things against Tottenham. Today it means a lot, the players were so aggressive. Everyone was like a machine.
“We play Napoli on Thursday and we have to react and be less naïve.
“Last season and this season we have been so poor in those terms but the spirit is there and the captains are fantastic.”
