The claim specifies the event took place on 'Saturday' and in 'Tbilisi'. However, the evidence shows that the 2025 European Judo Championships were held in Podgorica, Montenegro, and the evidence mentions a win on 'Friday' in that location. Furthermore, Wikipedia indicates that Tbilisi is scheduled for the 2026 championships, not the 2025 event. While Arbuzov won gold in the under-81 kg category at the 2025 European Championships, the specific date (Saturday) and location (Tbilisi) mentioned in the claim are contradicted by the evidence.

The claim suggests Arbuzov won a second gold following Murad Chopanov's win at -66 kg 'earlier this week.' While evidence confirms Arbuzov won gold in the under-81 kg event and that Murad Chopanov won gold at the European Championships, the evidence does not confirm that Chopanov's win occurred at -66 kg, nor does it establish a direct sequence or context that makes Arbuzov's win a direct follow-up to Chopanov's win in the manner described. The evidence is insufficient to corroborate the specific sequence or the weight class for Chopanov's win relative to Arbuzov's win.
