The full-back has not featured for the Reds since suffering an ankle injury in December, with Andy Robertson having since made the left-back position his own.
Moreno is now back to fitness and ready to return to the first-team reckoning, although he admits he faces a tough task in toppling his team-mate from the starting XI.
“It’s always tough to get your place in the first team at Liverpool Football Club," he told Liverpool's official website.
“Obviously, as a result of my injury, Robertson has taken his chance and grabbed it with both hands. But I‘m training really hard now and determined to do all that I possibly can through hard work to try and win my place back.”
