Real Madrid have agreed a €50million (£42.6m) deal to sign Porto defender Eder Militao, Globo reports.
The 21-year-old has impressed for Porto, since arriving in a €4m (£3.5m) deal from Sao Paulo last summer.
He will now become Madrid's first summer signing for Zinedine Zidane, after the Spanish club agreed to pay his €50m buyout clause.
The report also claims that the Brazilian defender has agreed a six-year contract with the LaLiga giants and had a medical in Portugal on Monday.
Zidane returned to Madrid on Monday for his second stint as manager, following talks with the club's president Florentino Perez.
It is understood that in order to convince Zidane to come back to the Santiago Bernabeu, Perez has agreed to overhaul the squad in the summer transfer window and has promised to spend in the region of £300m on new players.
