Monaco forward Radamel Falcao should be the main contender to replace Luis Suarez at Liverpool, according to former striker John Aldridge.
The Reds failed to complete a deal to sign Loic Remy after the France international reportedly failed a medical leaving manager Brendan Rodgers to consider other targets.
Divock Origi has joined from Lille but will spend the coming season on loan at the Ligue 1 side, leaving Liverpool short up front and Aldridge says Falcao, who has been linked with a move to Real Madrid this summer, should be targeted.
"Personally I would like to see a full-back, a real classy full back who can inspire them," Aldridge said. "Moreno, I don't whether they can prize him away and pay lots of money.
"And a striker. I thought Remy for £8.5m was a very shrewd buy but it's fallen through for whatever reason, so Liverpool do need another striker in my opinion should something happen.
"Who is out there? Falcao, they're saying he had a horrendous season last year; he was a bit part of the player he was last season. If he can get back to where he was the previous season then he would be one wouldn't he?"
Falcao joined Monaco last season in a £50m deal from Atletico Madrid but failed to recapture the form that made him among the most feared forwards in world football, scoring just nine league goals during an injury-hit season.
Real, who added Falcao's former team-mate James Rodriguez to their squad this summer, have been rumoured with making a move for the Colombian international who missed the World Cup with a serious knee problem.
Liverpool do have Daniel Sturridge to lead their attack for the forthcoming season but with Fabio Borini's future uncertain and Adam Lallana set to miss the start of the season with a knee injury, the club are keen to reinforce the area.
