Which to upgrade first

Zendderman

I have about 140k to upgrade my team.
I have 3 options that I am looking at and I confused so need help.

1) Upgrade davinson Sanchez to van dijk
2) upgrade ederson to de gea
3) upgrade from 86 if arnautovic to aguero

Pls help
P.S- davinson is paired with kompany

I'm not a huge fan of using Kompany this year, but out of the three options I would also go with upgrading to De Gea.

Ederson to gea

I'd replace kompany with van Dijk definitely
