Liverpool manager Brendan Rodgers has identified left-back as an area he wants to strengthen amid speculation he is set to secure a deal for Valencia's Aly Cissokho.
Reports in Spain suggest an agreement is close to sign the 25-year-old on a season-long loan with a view to making the move permanent next summer.
Liverpool are currently preparing for the middle game of their pre-season tour to Asia and Australia as they face Melbourne Victory on Wednesday.
Rodgers revealed wants to bring in competition for Jose Enrique as he seeks to bolster an area he had difficulties with last season.
With Enrique out of favour 12 months ago Rodgers began the campaign by switching Glen Johnson to the opposite flank and blooding youngster Andre Wisdom, although the Spaniard eventually regained his place and enjoyed a good second half of the season.
"There are obviously certain areas of the squad where we're a bit thinner than others," he said.
"We probably need a bit more support - that extra bit of quality - at the top end of the field and that's something we'll look out for.
"That'll be mixed with needing cover in the left-back position - that's something we're looking at.
"It's not really about numbers, it's about quality.
"If we can do that over the next number of weeks we'll be happy."
