Liverpool are being linked with two players from Athletic Bilbao and one from Borussia Monchengladbach, according to reports in Spain.
The Reds signed Cody Gakpo from PSV Eindhoven during the January transfer window but they are expected to be busier in the summer as Jurgen Klopp looks to overhaul a squad that has badly under-performed so far this season.
Liverpool are currently 10th in the Premier League, following Saturday's dismal 3-0 defeat at Wolves, and are out of both domestic cups. While they remain in the Champions League, it is anticipated that the Reds, who last season went close to winning an unprecedented quadruple, will need to rebuild once the 2022-23 campaign comes to and end.
