Liverpool can't hang about if they wish to sign permanently Schalke defender Ozan Kabak.

Liverpool are leaning towards making Kabak's loan move from Schalke a permanent one this summer, says Fussball Transfers.

The Reds 'would have to activate' the €20m clause by the end of May at the latest – in other words, there's a deadline for them to meet.

It appears as if they may do so, though, with the 'inclination' at the club currently leaning towards making him a permanent member of the squad.

For their part, Schalke are determined to sell Kabak this summer, even if Liverpool fail to trigger his option.
