Liverpool appear to be keeping a close eye on Atletico Madrid and Spanish youth starlet Saul Niguez.
According to the Daily Mail, scouts from the Merseyside outfit were present during Rayo Vallecano's La Liga clash against title-chasing Atletico on Sunday evening to watch the highly-rated 19-year-old play.
It is unclear if those Liverpool scouts would have been particularly impressed with what they saw at Estadio de Vallecas, however, with versatile defender Niguez - currently on loan at Vallecano - having an evening to forget after scoring an own goal in an emphatic 4-2 defeat against his parent club.
If Liverpool do intend on pursuing a deal for Niguez, with reports suggesting that they held talks with the player's father last week, then they could face significant competition from Premier League rivals Arsenal and Manchester United.
Niguez, who has made six appearances for Spain's U21 side, joined Atletico back in 2010 after a period with cross-city rivals Real.
He made a handful of appearances at the Vicente Calderon before joining Vallecano on a season-long loan deal in July and has formed a crucial part of Paco Jémez's side.
Despite his relative inexperience at the elite level, though, it appears as if any potential suitors will have to dig deep in order to sign Niguez with his contract supposedly containing a fixed fee clause of £20 million.
Manchester United, who completed the signing of Chelsea midfielder Juan Mata at the weekend, will presumably keen to further strengthen their squad following such an impressive capture that appears to have galvanised supporters at Old Trafford.
Liverpool, meanwhile, who advanced to the next round of the FA Cup after a 2-0 victory over Bournemouth on Saturday, have seen their squad depth called into serious question of late following a succession of unfortunate injury problems and could certainly be boosted by improved squad numbers.
