Carlo Ancelotti will announce the list on May 18. Until then, there will be 14 matches for Santos all competitions. The tendency is for Neymar to play in at least half (7).
If he gets called up by Carlo Ancelotti, the tendency is for Neymar to NOT play any games for Santos after the announcement in order to preserve himself & be ready for the friendly on May 31st. The focus is to avoid even minor muscle injuries.
