Liverpool great John Aldridge believes the club's owners won't dip into their own pockets this summer market.
Aldridge wrote for the Sunday World: "Liverpool's owners showed in January that they are not ready to splash the cash, so selling players to finance new arrivals may be the route they follow once again.
"Now they need to look at the players they don't need, and maybe even consider a sale of one of their big-hitters to raise funds, as this team is clearly in need of some fresh blood.
"I suspect Joel Matip, Marko Grujic, Xherdan Shaqiri, Harry Wilson, Naby Keita and Divock Origi will all be made available for sale by Liverpool this summer – if Firmino was added to that list, it would generate funds of around £100m.
"There may also be a decision to make over Salah's future, as he has not tried to hide his interest in a move to Real Madrid.
"If they were to sell a player of Salah's stature, Klopp would have a big transfer kitty to work with and he will need to bring Liverpool back to the top."
