Monaco announced on Tuesday that Brazilian right back Fabinho's loan from Portuguese outfit Rio Ave has been made into a permanent deal.

The 21-year-old, on loan at the Principality side since July 2013, has signed a contract until June 2019.

Fabinho has been a regular fixture for Monaco this season, making 35 Ligue 1 appearances and reportedly attracting keen interest from Spanish champions Barcelona.

Fabinho is a Brazil U20 international and has earned a call up for the Copa America starting this month in Chile.

Monaco also said that defender Almamy Toure, 19, had extended his stay for four years.
