Barcelona are poised to formally open the bidding for Luis Suarez this week.
Club intermediaries believe they already have an accord in principle with the player and his representatives but Barca must now match Liverpool's £80m valuation.
Although Liverpool have an interest in Alexis Sanchez, the Chile star is keen to stay one more year at Barcelona which may also frustrate other suitors Arsenal, Manchester United and Juventus.
Real Madrid maintain an interest in Suarez but they have opened preliminary talks with Monaco over a deal for Radamel Falcao.
Liverpool are pressing ahead with deals for Southampton's Adam Lallana, Benfica's Lazar Markovic and Lille's Divock Origi. Although Tottenham have made a late move to sign the Belgian striker he is expected to sign for Liverpool for £9.8m.
Liverpool are unperturbed by Real Madrid's interest with Raheem Sterling. The England international signed a long-term contract 18 months ago which incorporates annual increments.
