That's btw a really big big issue for France if it is a France - Swiss because:
- Roland Garros is an open stadium so impossible to play in November at that place w/ the cold in France
- Bercy is in work and open only for ATP Bercy so unavailable..
And there is no other place in France adapted for such a big event..
The same problem had Czechs in 2012 with their O2 Arena but they moved some concert 2 months later. But I see this will be impossible with Bercy because there are 3 concerts by 3 different artists at the time of the Final.
