One notable incident at Manchester United involved a disagreement with coach Ruben Amorim. Garnacho was left out of the starting lineup for a Europa League final, which United ultimately lost. He publicly expressed his frustration and hinted at possibly leaving the club. Additionally, his social media behavior and his brother's criticism of United management didn't sit well with Amorim.

When Garnacho arrived at Chelsea, he was behind his teammates in terms of fitness due to a lack of pre-season training. His first start for Chelsea came in a League Cup match against Lincoln, where he played solidly but didn't make a significant impact. His first Premier League start was against Liverpool, where he was Chelsea's main attacking threat, targeting right-backs and creating scoring opportunities.

Since then, Garnacho has become the preferred left winger under manager Enzo Maresca, who has praised his progress. The young player has scored two goals in six starts for Chelsea, including a crucial equalizer in a 2-2 draw with Qarabag. Maresca has expressed faith in Garnacho's ability to make a difference in big games.

Maresca acknowledges that Garnacho needs nurturing and has been working to manage his physical condition, which wasn't up to standard when he arrived. The Italian coach believes Garnacho is improving and is happy with his current performance.

Despite a disappointing draw with Qarabag, Maresca praised Garnacho's efforts, saying he's slowly but surely improving. Chelsea fans and pundits may have initially questioned Garnacho's behavior and potential, but he's now speaking for himself on the pitch, which could lead to him becoming a top player for the club.
