The Daily Mail reports that Leeds manager Marcelo Bielsa is keen to bolster his defensive options after injuries to Diego Llorente and Robin Koch have disrupted his first-team selections this term.
Nkoulou, who will see his contract expires in June, has previously been linked with Arsenal, Tottenham Hotspur and Newcastle United as well as Ligue 1 champions Paris Saint-Germain.
The 30-year-old began this campaign as one of Torino’s first-choice centre-backs but was dropped in November, following the club’s poor run of results.
The Cameroon international has recently been self-isolating after tested positive for coronavirus, but he is hoping to return to action soon.
However, the centre-back will consider his options if he fails to nail down a regular place in the first team.
