奥巴梅扬：当年我从巴萨去切尔西是一个巨大的错误（奥巴梅扬懊悔：离开巴萨转投切尔西是我职业生涯的重大失误）

Gathering context on Auba

I think it’s best to clarify what context we're discussing, such as quotes, career timeline, and stats from his time at Chelsea versus Barcelona and Marseille. I remember he moved to Barcelona in January 2022 and then to Chelsea in September 2022, but things didn’t go well after that due to managerial changes. Most notably, he had impressive performances at Marseille in 2023-24, possibly becoming the Europa League top scorer with over 10 goals. I want accurate details, so I’ll avoid any made-up specifics.Summarizing Auba's time at Chelsea

I can recap the timeline of his moves and the challenges he faced at Chelsea, like managerial changes and squad issues. I want to keep it concise and clear. So, I’ll ask if the user needs more details or just a quick overview. My bullet points could include: Tuchel was sacked shortly after Auba's signing, and then Potter took over, followed by Lampard as interim. Auba scored only 3 goals in 21 appearances at Chelsea, which is a significant point to highlight.Summarizing Auba's performance and challenges

Auba was omitted from the UEFA Champions League knockout list in February 2023. At Barcelona, he scored 13 goals in all competitions during the 2021-22 season, including 2 goals against Real Madrid at the Bernabéu. Although he had good form, Barca didn’t win La Liga that year or the next during his time there. Key points to mention on his time at Chelsea include Tuchel's sacking shortly after Auba's arrival and system mismatches under subsequent coaches. I can offer a side-by-side stats table if needed, but I'll keep the presentation light and casual.
