Highly-regarded Brazilian teenage attacking midfielder Otavio signed for Portuguese side Porto on Monday from Internacional Porto Alegre for a fee reported to be 7million euros ($9million).

The 19-year-old, who had been with Internacional for three years, signed a five year contract with Porto which includes a buyout clause of 50million euros.

Otavio could find himself making his Champions League debut this month when the campaign begins with Porto drawn in Group H along with Ukraine's 2009 UEFA Cup winners Shakhtar Donetsk, Spanish outfit Athletic Bilbao, making their first appearance in the group stage for 16 years, and Belarus minnows BATE Borisov.
