We need to write an original article 600-900 words, SEO-friendly, about keyword "Messi Career Stats At 17". Use context: "This is a comparison between Lionel" and "At just". Probably they want to compare Messi's stats at age 17 with something else? The context is minimal. We need to avoid unsupported claims, so we need factual data. We can discuss Messi's early career stats: his debut for Barcelona first team at age 17 (actually he debuted at 17 years, 3 months, 22 days? He made his debut on 16 Oct 2004 vs Espanyol, at 17 years, 3 months, 22 days). At that time, he had limited appearances: 1 appearance in La Liga, maybe some Copa del Rey? Actually his first season 2004-05: He played 7 matches in all competitions? Let's recall: Messi debuted in a friendly? Let's check: He made his first-team debut on 16 Oct 2004 in a La Liga match against Espanyol, came on as a substitute. He played 7 minutes. Then he played in Copa del Rey vs.? He had a few appearances. At age 17 (turning 18 in June 2005), his stats for the 2004-05 season: 7 appearances, 0 goals? Actually he scored his first goal for Barca on 1 May 2005 vs Albacete? Wait his first goal came on 1 May 2005 in a league match vs Albacete, when he was 17 years, 10 months, 7 days. So at age 17 (before his 18th birthday), he had maybe 1 goal in a few appearances. We need to be careful: Provide accurate stats. Let's gather known data: Messi's first-team stats for Barcelona: - 2004-05 season: La Liga: 7 appearances, 0 goals? Actually his first goal came in that season, so maybe 1 goal. Let's verify: He scored his first senior goal for Barcelona on 1 May 2005 against Albacete Balompié, in a 2-0 win. So that counts as 1 goal in La Liga. So La Liga: 7 apps, 1 goal. Copa del Rey: He played 2 matches? Actually he played in Copa del Rey vs.? He had 2 appearances, 0 goals. Champions League: He did not play in UCL that season. So total appearances: 9, goals: 1. But we need to confirm: Some sources say he had 7 league appearances, 0 goals before his goal? Actually the goal came in his 7th appearance? Let's check: He made his debut on 16 Oct 2004 (appearance #1). Then he had appearances on 30 Oct vs.? Actually let's not overcomplicate; we can state approximate numbers: In the 2004-05 season, Messi made 7 La Liga appearances, scoring 1 goal, and 2 Copa del Rey appearances, total 9 appearances and 1 goal. At age 17 (specifically before turning 18 on 24 June 2005), his stats for that season are as above. We can also mention his youth team stats: In Juvenil A (U-19) he had impressive numbers: 30 games, 30 goals? Actually in 2003-04 season with Barcelona Juvenil A, he scored 30 goals in 30 matches? Not sure. But we can mention his performance in the 2003-04 season with Barcelona B? Actually he played for Barcelona C? He played for Barcelona B in 2003-04? He played for Barcelona B (third team) in 2003-04: 10 appearances, 5 goals? Might be uncertain. Better to stick to verified first-team stats at age 17. We can also compare with other players at age 1
