This is why we we need to chill and wait for all the info before analysing and having mini meltdowns.
Even this above news we need to wait til is fully confirmed. Tho Porto fans I know say it's common knowledge he has 30m release clause that can increase if not exercised.
I guess it will depend on games, formation, and opponents. Sometimes Yildiz can be an AM, other times operate as a LW, and sometimes he might be benched or injured
