Barcelona are in talks over £250 million to sell Camp Nou naming rights to the largest stadium in Europe, since 1957.
The Blaugrana have confirmed they are in negotiations with two or three companies over the rights, which already holds a capacity of 99,345.
The naming rights deal forms part of a planned renovation of the stadium and surrounding area, with Barcelona keen to keep the proposed cost of the scheme to £500m.
Club president Josep Maria Bartomeu was in London to watch Barcelona draw 1-1 with Chelsea in the UEFA Champions League on Tuesday and, as part of his visit to the English capital, spoke about the current La Liga leaders' desire to revitalize their home of the past 50 years.
Speaking about the club's finances, Bartomeu told Bloomberg: "Beko was the last [sponsor] that we renewed our agreement with, the next steps are the naming rights to the stadium.
"Espai Barça is a total renewal of the stadium, but not only the stadium, also part of the city of Barcelona, because we will have a new arena.
"There are two of
three companies we are talking to. Our partner will probably bring us half of the investment.
"One of the objectives of the club is to earn money every year, of course, because we have to reinvest that money in players and real estate."
Barcelona host Girona in the week 25 of the La Liga on Saturday evening.
