Liverpool are in direct competition with their local rivals Everton as both clubs step up their interest in Granada left-back Guilherme Siqueira.
The 27 year old has been linked with a possible move to Real Madrid as the Spanish giants look to find a possible replacement for Fabio Coentrao who is expected to leave the club after a somewhat disappointing stay at the Bernebeu.
However, according to Spanish publication El Ideal de Granada, Liverpool and Everton are also keen to recruit the experienced defender as both clubs look to find cover for their current first choice left-backs.
Everton are concerned that Manchester United will come back in with an improved offer for Leighton Baines, while Liverpool boss Brendan Rodgers has revealed that he feels he needs cover for Jose Enrique.
Siqueira would be somewhat of a surprise as the Brazilian has been with La Liga minnows Granada for the past three seasons, but his consistent performances have clearly caught the eye.
The left-back has admitted that he will take some time to consider his future but it is unlikely that he would turn down an opportunity to move to Merseyside, as both clubs are expected to challenge for a place in the top six next season.
Granda are believed to have inserted a €25m release clause in the contract Siqueira signed last summer which keeps him at the club until 2017, but it is highly unlikely that either club would be willing to spend this amount on the defender.
While Liverpool are merely seeking a back-up option for Enrique, Everton's need for a left-back could become a priority if United come in with an improved offer for Baines.
They have already had an offer of £12m rejected but with more than a month until the transfer window closes there is a chance that David Moyes could attempt to be reunited with the defender at Old Trafford.
