Pep Guardiola has identified the decision to let Joe Hart leave Manchester City as the biggest regret of his time at the club. Guardiola admitted that, despite making numerous decisions during his tenure, he deeply regrets not giving Hart the opportunity to prove himself under his management.
The former England goalkeeper was a key figure at City before Guardiola's arrival, but was ultimately moved on as part of the manager's squad overhaul. Reflecting on that period, Guardiola acknowledged that allowing Hart to depart without a proper chance to adapt was a significant misstep.
