Liverpool has agreed a deal to sign Aly Cissokho on loan from Valencia.
However, the 25-year-old left-back, who has one France cap, will not be available for the opening match of the season against Stoke on Saturday.
He is expected on Merseyside next week to finalize a move which could become permanent next summer.
Manager Brendan Rodgers had wanted to sign another left-back, Guilherme Siqueira from Spanish club Granada, but the clubs failed to agree a fee.
Liverpool is keen to bring in one more attacking player before the transfer window closes and have made an enquiry for Anzhi Makhachkala forward Willian.
At this stage, the Anfield club is one of a number of options for the former Shakhtar Donetsk player, who came close to joining Tottenham in 2012.
Liverpool has yet to make a formal offer but the fee would be a minimum of £25m. The Anfield hierarchy is, however, confident they can complete the deal.
Willian has become available after Anzhi made several high-earners available for transfer as they attempt to cut costs dramatically.
Liverpool manager Brendan Rodgers is keen to add to his attacking options after missing out on Henrikh Mkhitaryan, who joined Borussia Dortmund from Shakhtar Donetsk, and Atletico Madrid's Diego Costa after the Brazilian signed a new three-year contract with the Spanish side.
