My wild unfounded musings are that over the last few days there seem to have been a few bits from Tonda, that along with him being in the stand to try that out lead me to think that the club have been told off the punishment and it is not too severe and possible a touchline ban.
I also think the reason we have not heard is we have appealed, don't think anything was released publicly about Chelsea until after the appeal.
As I say just my musings.
