Pep Guardiola has acknowledged a potential 'mistake' in allowing Julian Alvarez to leave Manchester City for Atletico Madrid without a direct replacement. Alvarez's departure, for a club-record fee of £81 million, has left City reliant on Erling Haaland as their only out-and-out striker, prompting concerns over squad depth in case of injuries. Guardiola expressed happiness with the current squad but admitted that the situation could pose problems if injuries occur. He stated that several players can fill Alvarez's role, although they are not direct replacements for Haaland. Despite being linked with replacements, City did not secure any before the transfer window closed, with only two signings made this summer. Guardiola emphasized the importance of player involvement for team performance and noted that they will have opportunities to strengthen in the winter transfer window.
