Schira, Sky, you, me: doesn't matter. I'll go by the official statements.
Official statements NEVER say anything about wages. You can read them all. (What they do usually mention is the length of the contract.)
The 7, or possibily 10, million is what we're going to pay Porto.
So, 2 options:
Option A, salary included: According to our payroll, he's going to earn €0. Porto are still paying his wages, out of what we paid them for the loan.
Option B, salary not included: Wages on our payroll currently unclear afaik, but we'll find out what they are in due time.
Now, option B sounds a lot more likely, but I obviously don't know. I'm sure as shit not going to just assume it's option A, though.
