Boca play their 1st game at home for the Libertadores, using San Lorenzo's stadium as La Bombonera is suspended for the first 3 home games in this year's Libertadores.
San Lorenzo have played "their game" ... facing Boca on Sunday for the local tournament, they have left on purpose the grass really tall, which added to an unusual heavy rain, all day today, will make the pitch heavy and slow. The intention is to get Boca's players more tired than normal for their game in 72 hrs. Attendance will be affected due to trains and streets flooded in Bs As.
Cienciano will try to gain their first points after dropping all 3 in their home game against Toluca. They have faced Boca only once before ... a pk shoot-out that gave them the South american Recopa in 2004.
