Theres two points here really...
1: Did he have a clause in his contract allowing him to jump ship for free -- other posters have said weve been paid north of £10mil.
2: No matter what was in his contract or agreed verbally it goes against everything he has stated verbally (and in writing) in the book, after PSG and onwards...many times, concerning wanting to build a team over the long term...and specifically Everton.
I think its reasonable to assume that the bloke either dramatically changed his decades long wish or he had been lying.
Id go with the latter.
As a non commercial lawyer I would strongly suspect that there was a release clause in the contract.
Remember back 18 months. Moshiri was desperate ( again ) and pulled off what was regarded as a huge coup in getting Ancelotti.
Ancelotti held all the cards and I imagine that as a savy operator either he or his lawyer insisted on a release clause , prehaps for free or maybe a fixed amount , if a CL club came in for him.
However you are totally correct about loyalty and integrity.
"Quiet Leadership" says that those are the 2 qualities he values most. Yes he thought PSG was a project and that's what he wanted and to be loved and wanted.
He had all that here said he wanted to extend his contract and lead us into the new stadium.
Even worse the hypocrite was an arch critic of the ESL and yet at the 1st opportunity jumps ship to join the founder of it.
We are better off without him.
