someone could help me please?

You are right.
You need to divide Value by Wage and then look in the table for the closest quality for comparison (ignore levels completely: quality matters, levels don't). When choosing, don't pay attention to the Wage -- all players of same quality have the same Wage.
The table is not very detailed, so gather your own data too, it will help you greatly.
