City made a very fast start to the game as Raheem Sterling opened the scoring in the first minute.
"So now we need only to understand the reason why at the moment it isn't working".
Higuain played all 90 minutes against City but had little service to work with as the visitors enjoyed only 44 per cent possession. We need to understand the reasons.
Guardiola is aiming to become the first manager in more than a decade to win back-to-back Premier League titles and has challenged his side to replicate the desire of his old club that won three La Liga titles and two Champions Leagues during his time there.

City have now scored 33 goals in their last five home games in all competitions and have a chance of lifting their first silverware of the season when they face Chelsea again at Wembley in the League Cup final on February 24. Abramovich demands Champions League football, and Sarri is increasingly in danger of failing to deliver a top-four finish. At the moment I am not able to see the reason.
