Liverpool's principal owner John Henry has suggested supporters' protests over ticket prices have put plans to further expand Anfield in doubt.
Liverpool fans staged a mass walkout in the 77th minute of a game against Sunderland in February after the club's owners, Fenway Sports Group (FSG), planned to increase ticket prices at Anfield. FSG later apologised and scrapped the plans to increase the cost of tickets.
The recent redevelopment of the Main Stand has taken Anfield's capacity to over 54,000 and has helped close the gap on rivals in terms of matchday revenue, according to chairman Tom Werner.
There is reportedly outline planning permission already in place for an extra 4,800 seats in the Anfield Road end, but Henry says the next stage of the stadium's redevelopment may not go ahead as it might not make economic sense.
"I don't know if there is a next step because ticket prices are an issue in England," Henry told reporters. "That may foreclose further expansion. We'll have to see."
Meanwhile, Henry, who was speaking in New York on Tuesday, believes there is no one more suitable than Jurgen Klopp to manage Liverpool.
Sources told ESPN FC in June that FSG's commitment to Liverpool was waning before the appointment of Klopp in October reignited their engagement.
FSG handed Klopp a new six-year contract in July after guiding the club to two cup finals in his first season in charge.
"He was a perfect fit for Liverpool, for the culture of the club, for the supporters, for the kind of team that we were trying to build," Henry added. "We couldn't have asked for a better fit."
