Liverpool posted a scout to watch a promising centre-back Goncalo Inacio in Portugal last weekend.
Correio da Manha says the Reds are keeping tabs on Sporting Lisbon defender Inacio.
A scout was present as he turned out against Porto on Sunday - a match that away team Porto won 2-1.
The report also claims that following the visit, Liverpool 'could' now make a move for the Inacio at the end of the season.
