Back in 2006 (Stankovic Cup in Nanjing), Splitter wore #15 for Brazil and got involved in a China–Brazil scuffle. You can find Splitter from 01:15 in this Youtube video.
Chinese sports media recently resurfaced this old incident, and it’s a classic “wait… THAT’S our guy?” moment. Some fans are jokingly tying it to the current Yang–Splitter relationship — nothing serious and just pure speculation.
