The league leaders have been undone over recent days by conceding batches of goals in quick succession - a problem the manager has faced before
Manchester City manager Pep Guardiola concedes he must solve vulnerabilities in his teams when it comes to conceding clusters of goals in quick succession.
City passed up the chance to seal the Premier League title in memorable style on Saturday as they let a 2-0 half-time lead against Manchester United crumble, their bitter rivals going on to a 3-2 victory that stunned an Etihad Stadium primed for celebration.
Paul Pogba netted twice in the space of 97 seconds to cancel out City's goals from Vincent Kompany and Ilkay Gundogan with 55 minutes on the clock and Chris Smalling headed a 69th-minute winner.
That 16-minute collapse followed three Liverpool goals in the space of 19 first-half minutes at Anfield last Wednesday, leaving City facing a daunting 3-0 deficit in the second leg of their Champions League quarter-final next week.
A similar nightmare spell brought about City's only other defeat to Premier League opposition this term – a 4-3 reverse at Anfield in January – and Guardiola acknowledged this anomaly is a concern that has haunted him previously in his coaching career.
