Based on my research, here is my analysis of the claim:

Reasoning:

• The claim states Raphinha (Brazil) was the sole top goalscorer in the Champions League in 2025 with 13 goals¹²³.
• According to UEFA's official statistics and Wikipedia's records, the 2024-25 UEFA Champions League season (concluding in 2025) had two players tied as top scorers with 13 goals each: Serhou Guirassy (Borussia Dortmund) and Raphinha (Barcelona)³²¹.
• Raphinha did score exactly 13 goals in 14 matches for Barcelona during the 2024-25 Champions League campaign²³.
• However, he shared the top scorer award (Golden Boot) with Guirassy, who also scored 13 goals in fewer minutes (1,084 vs Raphinha's 1,224), which is why Guirassy was awarded the official Golden Boot⁴.
• The claim implies Raphinha was the sole top scorer by using the singular "top goalscorer," which is inaccurate since there was a tie¹²³.
