Liverpool are close to completing a loan deal for Schalke's Turkey central defender Ozan Kabak.
The 20-year-old will join Liverpool until the end of the season in addition to the deal which brings Preston North End's Ben Davies to Anfield for £2m.
Marseille's Duje Caleta-Car is also a potential target with the Reds exploring a number of options in defence because of injuries.
Kabak was recommended by former Huddersfield Town manager David Wagner.
Wagner coached him at Bundesliga side Schalke and worked with Liverpool manager Jurgen Klopp at Borussia Dortmund.
Liverpool have an option - not an obligation - to buy Kabak at the end of the season and will pay a £1m loan fee now with a potential for a £500,000 bonus based on games and how they fare in the Champions League.
