Zohore's new contract

Anybody know any details about this? How long is it? Is there a sell on clause? Buy out clause? What wages is he on?
Just wondering if he hits the floor running next season and struggling prem or big money champ teams inevitably come looking for a goal scoring panic buy come January, if we can actually keep hold of him or what we can get out of the sale

All we know so far is that he has it written into his contract that he arrives at the ground at 6:30pm for an evening kick-off.

Any attempts to make him arrive earlier will make him tired and he will need a nap between 5pm and 6pm.

Im sure I read its until 2020
