I want to know the answer to the following question:
Nwankwo Kanu won in what championship league?
All the background I'm provided with is that "The nation's cadet team from Japan '93 produced some international players notably Nwankwo Kanu, a two-time African Footballer of the year who won the European Champions League with Ajax Amsterdam and later played with Inter Milan, Arsenal, West Bromwich Albion and Portsmouth.". Is that enough to answer the question?
Answer: yes
