The reaction from the club will be telling.
If they actually do something today/tomorrow/next few days, then it will demonstrate that Martinez has been living on borrowed time and that the semi final defeat was the last straw. This is preferable, as it shows a change in mindset since Mosh bought in.
If, as usual, they remain tight lipped, anything can happen - i.e. - we 'reluctantly' release him in the Summer, or worse still - he's still in charge at the start of next season. This would indicate our board haven't changed one bit and will serve as a signal that we should resign ourselves to indefinitely using the phrase 'Everton that'.
