Steven Gerrard has named the two positions where Liverpool must sign “big pieces of the jigsaw”.
The Reds have made just one signing so far this summer, with striker Dominic Solanke to arrive from Chelsea when his contract with the Blues expires on July 1.
They have been linked with a number of other names, including RB Leipzig midfielder Naby Keita, while a move for Mohamed Salah continues to rumble on.
The club were thwarted in their attempts to sign Southampton’s Virgil van Dijk, but Gerrard does not believe that centre-half is a position Liverpool need particular improvements anyway.
He says Jurgen Klopp should concentrate on signing a forward player, most likely Salah, as well as a left-back.
“We’ve got a fantastic manager at the helm, who will hopefully attract a few big names to complete the jigsaw,” he told BT Sport.
“I think Liverpool are very, very close. If you look at the statistics in the top six, they’re the best team in terms of head-to-head.
“Liverpool know where they need to improve and it’s the consistency against the teams that are maybe in the bottom half of the table. The teams that sit narrow and compact, and are difficult to break down.
“But hopefully we can get the two or three big pieces of the jigsaw that are missing. I’m really confident Liverpool can keep moving forward and there will be success just round the corner.
“I think we need someone in the left-back position. James [Milner] has done a fantastic job, but it would be nice to have another option out there as well.
“And maybe one more attacking player, to give us a bit more firepower and help us unlock these defences that are playing really narrow and compact.
“But I don’t think we need major construction, I think it’s just a couple of the pieces of the jigsaw left, and I’m really happy with where we are at the moment.”
