Palmeiras winger Estevao Willian will either be playing his final match for his boyhood team on Friday, or knocking his future employers Chelsea out of the Club World Cup.
The 18-year-old's date with destiny comes after Chelsea signed the latest Brazilian sensation for an initial £29.1m, with £19.7m due in add-ons, last summer - before allowing him to stay with his current club for another year.
And, after beating competition from the likes of Real Madrid and Barcelona, the Blues also agreed for Estevao to play for the Sao Paolo outfit in the Club World Cup before joining Chelsea.
