Okay, the user wants an article about Messi's career earnings at Barcelona. Let me start by outlining the structure. The main sections would be an introduction, his early years at Barcelona, peak earning years, later years, and his move to PSG and Inter Miami. I need to make sure to include the context provided, like the "4 euros per second" figure and the mention of his time at PSG and Inter Miami. First, the introduction should set the stage by talking about his legendary status and his financial journey. Then, in the early years, I'll mention his initial contract and how his earnings grew as his career progressed. I need to highlight key periods, like when he started earning more after winning major titles. The peak earning years would be when he was at his best, maybe around 2010-2015. I should include specific figures if possible, but the user didn't provide exact numbers, so I'll use the 4 euros per second as a reference point, maybe citing it as a commonly reported figure. In the later years at Barcelona, I should note the decrease in his salary due to his reduced role and the club's financial issues. Then, moving to PSG and Inter Miami, I need to mention his higher earnings there, but also the context of his club moves. I need to make sure the article flows naturally, with each section building on the previous one. Avoid unsupported claims, so I'll stick to the information given and any well-known facts. Also, use the required HTML tags and keep the word count between 600-900 words. Let me check the word count as I go. Wait, the user mentioned "Messi Career Earnings Barcelona" as the keyword. I should focus mainly on his time at Barcelona, but also touch on his moves to PSG and Inter Miami as they relate to his overall career earnings. I need to integrate the context points like the 4 euros per second, mention the Prime Football video, and include the hashtags if appropriate. But since it's an article, maybe the hashtags aren't necessary unless they fit naturally. Also, the user provided some phrases like "Welcome to Prime Football" and "Subscribe here..." which might be part of the original content they want included. However, the article should be original, so maybe those are just context for style or references. I should avoid markdown and use only the allowed HTML tags. Let me start drafting each section, ensuring that each heading is properly formatted with h2 or h3 tags. Wait, the user's example response includes sections like "Early Years at Barcelona," "Peak Earning Years," "Later Years and Reduced Role," and "Move Beyond Barcelona." That structure works well. I'll follow a similar approach to maintain consistency. Need to make sure that all the context points are included. The 4 euros per second is a key figure, so I'll present that as a commonly cited amount. Also, mention his move to PSG and Inter Miami, as they are part of his career earnings beyond Barcelona. Check for any unsupported claims. For example, if I mention specific salary figures, they should be based on the provided context or well-known data. Since exact numbers aren't given, using the 4 euros per second as a reference is acceptable. Also, the article should be SEO-friendly, so including the keyword "Messi Career Earnings Barcelona" in the title and throughout the text naturally. Let me start writing the introduction, then each section, ensuring that each part connects logically. Keep paragraphs concise, use bullet points or lists where appropriate, but since the user wants HTML tags like ul and li, I can use those for key points. Wait, the example response uses h2 and h3 tags. I'll structure the headings similarly. Also, the user's context includes "When it comes to measuring the greatest players in the world's most beautiful game, the focus inevitably turns to a pair of rivals..." but that might not be directly relevant here unless it's part of the flow. Maybe it's just part of the context they provided but not needed in the article. I need to ensure that the article is original and not just a paraphrase of the context. Use the context to inform the content but present it in a new
