Quite frankly I thought Sir Alex's behaviour was way out of line. So he apologised - and i don't think for one minute that Pietersen just took it like that. However, I'm sure they sorted it out behind closed doors and the acceptance of the apology by Pietersen was just that - and sufficient for the public.
I have to wonder about who the camera men were. It they were English sports reporters then more than likely they knew exactly what they were doing and who the women were, if the report Stanford made is true.
