The Spain international has proven a divisive player in the Reds camp since his move to Liverpool FC in a £14m deal from La Liga outfit Sevilla in the 2014 summer transfer window.
Moreno made a number of costly mistakes during the 2015-16 season after Jurgen Klopp took over the reins from Brendan Rodgers back in October 2015.
The 25-year-old produced a disastrous performance in Liverpool FC’s 3-1 loss to his former club Sevilla in the Europa League final in Basel in Klopp’s first season.
The Reds boss decided to use midfielder James Milner in an unorthodox left-back role throughout the 2016-17 season to cast doubt on Moreno’s future at the club.
The Spanish defender appeared to be heading towards the exit door following the arrival of Andy Robertson in an £8m deal from Hull City last summer.
However, Moreno started the current campaign as first-choice before an injury setback during a 7-0 win over Spartak Moscow in the Champions League group stage.
Former Liverpool FC left-back Riise, who was heavily criticised during his final season at Anfield, lifted the lid on his text message of support for Moreno.
“He worked really hard, kept himself fit and I’m very happy for him as he was able to prove how good a player he is,” Riise told Liverpool FC’s website.
“I’ve sent him some messages just to tell him how pleased I am for him and how he turned it around and that he must now continue working hard.”
