The 20-year-old Spaniard arrived from Cadiz in 2010 having starred for the Spanish Under-17 side, and came to Anfield with high hopes of being the next big thing. His most prominent season came in 2012-13, when he made 20 appearances in all competitions, and seemed poised for a bigger role under Brendan Rodgers.
Yet there was a surprise last summer as Liverpool chose to loan the youngster back to Spain with newly promoted Almeria. Suso played a key role for the club as they scraped La Liga survival by just one point, scoring three goals and notching up nine assists in an impressive season.
There has been plenty of talk about returning loanees Oussama Assaidi of late, but little has been said about Suso's future - until now.
Portuguese giants Porto have a reputation for signing young players before developing them and selling them on for large profit - as has been the case with the likes of Pepe, Anderson, Falcao, Hulk and James Rodrigez. Now it seems that new manager Julen Lopetegui - who has worked with Suso in the Spanish youth setup - has singled the Liverpool star out as a potential signing.
Liverpool seem willing to let the youngster leave the club in order to play first-team football, but allowing him to go permanently could be a mistake from Rodgers.
The Reds are obviously in the market for more attacking midfield help having missed out on the likes of Henrikh Mkhitaryan, William, Mohamed Salah and Yevhen Konoplyanka, and owning a young playmaker who could fill that role appears to be what Rodgers wants - yet it seems Suso is set to leave the club.
Given Porto's recent track record with developing players, it would be no surprise to see Suso progress as a player before coming back to haunt Rodgers and Liverpool.
