Matos will take on a responsibility to help talented Liverpool starlets bridge the gap between the Academy and Melwood.
The role was previously performed by Pepijn Lijnders before he was promoted from first-team development coach to assistant manager by Jürgen Klopp following the departure of Zeljko Buvac.
Matos previously worked alongside Lijnders at Porto.
He has filled in a number of roles with the Portgueuse club and is currently the assistant manager of their B team.
