Liverpool are looking at the "viability" of expanding Anfield further with the current rebuild of the Main Stand almost complete.
Andy Hughes, Liverpool's chief operating officer, told the Liverpool Echo that the club have had outline planning permission in place for the Anfield Road end since 2014, and are now looking at the design and cost of any redevelopment.
Further enhancements of Anfield could take its capacity into the region 60,000 -- in line with the attendances of most of their major rivals in the Premier League.
"We always said that we would complete the Main Stand and assess its success before looking at any development for Anfield Road," Hughes said.
"Anfield Road provides an opportunity to further develop our stadium in the future and the club's position is that we're going to start exploring the viability.
"We will follow the same robust process for Anfield Road as we did for the Main Stand. We are currently working on design, feasibility, cost, capacity and economic viability options.
"Only once we have completed this comprehensive process and come to a conclusion will be it be the right time to move forward with any development programme."
Liverpool's new-and-improved Main Stand, which has increased capacity by 8,500, has raised hospitality revenue streams for the club.
Owners Fenway Sports Group have always been coy about committing to the redevelopment of the Anfield Road end, with principal owner John. W Henry recently suggesting supporters' protests over ticket prices put plans to further expand Anfield in doubt.
"There are lots of pluses and minuses from a financial point of view," Hughes added. "Putting hospitality seats in means there's a greater build cost. It's a simpler assessment without hospitality.
"It needs to work across many fronts. From a design point of view, operational point of view and financial point of view. We are exploring all those things. We haven't ruled anything in or out at this point."
Meanwhile, Liverpool have revealed that a new pitch will be installed at Anfield over the summer, improving the playing surface and overall quality of the pitch ahead of the 2017-18 season.
