Lubeka could be available for less than his €90 million (£78m/$106m) release clause, having made it clear to the club he would like to leave following the failure to qualify for the Champions League.

Liverpool face plenty of competition if they are to seal the deal. Bayern Munich and Tottenham want to sign the defender themselves, while Manchester United, Chelsea and Real Madrid have all reportedly shown previous interest.
