The Northern Irish manager has stated that the Spaniard has reacted well to losing his position in the Reds starting XI.
The left-back was signed by the Anfield outfit last summer but had an inconsistent first campaign in English football.
The Northern Irish manager has opted to play youngster Joe Gomez in both of the Merseysiders’ first two Premier League games this season instead of the former Sevilla man.
The teenager joined from Charlton over the off-season and has initially impressed with his maturity and physical attributes.
Rodgers has stated that Moreno was doing everything in his power to get back into the starting XI and was handling the disappointment of not playing well.
“Alberto has trained very well,” the former Swansea boss told the Liverpool official website.
“He understands the reasons why he’s not in the team at this moment, but he, like all the other players, it was very important for me to acknowledge to them that it will be difficult between now and the international break, especially if the team is winning.
“But there are going to be opportunities for players this season, and there are opportunities every single day in training.
“And Alberto has trained really, really well, with no drop-off in his enthusiasm. He has quality and knows the areas where we want to help him improve in.
“Then when he plays or comes on in the game, he can make a contribution, and I thought he did that very well.”
Liverpool will travel to face Arsenal this Monday night in a mouthwatering clash, with the visitors hoping to avoid a similar result to the last time they featured at the Emirates Stadium - a 4-1 defeat.
Gomez will most likely get he nod again to start at left-back and will be tested against Aaron Ramsey and the Gunners attack.
