Manchester City is facing a challenging period after suffering their third consecutive defeat, a heavy 4-1 loss to Sporting Lisbon in the Champions League. Pep Guardiola remains defiant, stressing the need for improvement and stating, 'I won’t give up, that’s for sure.' The team's struggles are exacerbated by injuries to key players like John Stones, Ruben Dias, and Rodri, leading to the debut of 19-year-old Jahmai Simpson-Pusey in defense. Guardiola likened the current situation to his debut season in 2016-17, where the team managed to turn things around after a rough start. Despite the setbacks, he emphasizes that the squad is still in contention across all competitions and calls for collective effort to overcome this tough phase. City will look to bounce back in their upcoming Premier League match against Brighton.
