Much to Gaucho100K's annoyance last time I predicted a Boca win and was proved right.
This is a tougher one to call.........Boca seem to be changing their team about an awful lot and when Palacio and Palermo don't play they are very ordinary. River have been so so and haven't impressed much. So here is HIDDY's prediction for tomorrow.

If Boca have both Palermo and Palacio playing then BOCA to win. If they don't both play then a DRAW. RIVER won't win either way.
Sorry....you River fans out there.
