Golovin went to Monaco from CSKA last season for €30mil. Vlasic is performing at a higher level. So, theoretically should be at a higher value IF he keeps the same level over the season.
What are these whoscored stats for Sigurdsson having the 27th highest rating this season? Do you have a link...
How has Golovin done at Monaco Zat, you seen many of his games?
