I could only think of one ground over here that would be full to capacity if games were played on a Monday afternoon..... Anfield (as long as it didn't clash with signing on)Chelsea and City probably have small numbers of travelling supporters out in the USA. The BBC seems desperate to convince everyone that there is apathy for the tournament when most likely the Chelsea crowd was low because it was played in the afternoon of a working day between sides that have not got a big travelling support. The Boca game later in the day had a much larger crowd with 10s of thousands of Boca fans.
All major sporting events are staggered across the day for TV.
