You'll be happy with that surely
That would certainly be insulting for a coach of the calibre of Conte. I can see why he would reject it. Perez maybe adopting a cautious approach to save himself from huge pay-offs resulting from managerial sackings.
You are right. They should commit at least until June 2020.An interim contract is an insult to someone of contes caliber. He should be expecting and demanding more than that. You don't offer guys with his CV temp jobs.
About the pay offs I thought that we would have to pay the entire contract, but now Lopetegui only will get a year (6net),6 more if he doesn't have job in june 21 and all the contract if he is unemployed in 6/22(info from an ITK)
