In 2021 and 2022 we will have 19 players out of contract which will solve this issue.
I think that if we finish in europe this season Richarlison stays 1 more year.
We need to get players in though as at the moment it doesnt look like we'll be taking any points from the firsr few games unless Richarlison basically wins them for us on his own.
It will only solve that issue if we are planning on not signing any players for the next 3 windows.
