The 27-year-old has been a standout performer for Granada since they returned to the Spanish top-flight two years ago and his ability from set-pieces situations even saw him was even the club's top-scorer in the 2011/12 season.
That statistic is slightly misleading as three of his six goals came from the penalty spot, but his speciality from set-piece situations is certainly a prominent characteristic in his game.
Indeed, such as been his impression on La Liga that Real Madrid are also said to interested in the former Udinese man as a backup to Marcelo should they manage to agree a deal that would see Fabio Coentrao leave the Spanish capital.
However, the worry for Liverpool fans is likely to be whether Siqueira is much of an upgrade on the Premier League side's current Spanish left-back Jose Enrique.
Whilst Siqueira's technical ability and attacking instinct are likely to find favour with Rodgers' football philosophy, Enrique offers extra strength, greater defensive awareness and has six seasons Premier League experience under his belt.
Like the majority of Brazilian full-backs Siqueira's natural instinct is to go forward and whilst the prospect of he and compatriot Coutinho linking up on Liverpool's left-side would produce some fantastic moves, it would also leave a backline not blessed with great pace exposed on the counter-attack and by diagonal balls into the space behind Siqueira.
The interest in Siqueira and another Spanish based left-back in Valencia's Aly Cissokho continues to show though that Liverpool are probably not getting full value for money when it comes to the exodus of talent from La Liga this summer.
At the top end Manchester City and Spurs have snapped up the talents of Spanish internationals Jesus Navas, Alvaro Negredo and Roberto Soldado, whilst Arsenal bought a more rounded left-back from Spain in Nacho Monreal in January.
Everton and Swansea meanwhile, have used their respective managers' knowledge and contacts in the Spanish game to pick up gems like Gerard Delofeu and Alejandro Pozuelo on the cheap.
Liverpool by contrast have splashed out nearly £7m on Luis Alberto who ninth-placed Sevilla loaned out to Barcelona B last season and whilst Iago Aspas is a highly gifted forward, his return of just 12 La Liga goals last season hardly inspires belief that he will be able to fill Luis Suarez's boots should the Uruguayan finally force his way out of the club this summer.
Siqueira also falls into this category. There is no doubting he is a talented player and would certainly be a welcome addition to Rodgers' squad given the lack of defensive options at his disposal.
However, he would be another new recruit who is unlikely to move Liverpool onto the next level they need to go if they are to reclaim a place in the top four and the much-needed riches of the Champions League.
