Barcelona are reportedly contemplating whether to make an offer for Antonio Rudiger and Fabian Schar.
At a time when Barcelona are dealing with significant financial issues, Ronald Koeman is having to make do without the services of key centre-back Gerard Pique.
The long-term injury to the Spain international is expected to lead to the Catalan giants bringing in a fresh option during the January transfer window.
According to The Athletic, Rudiger and Schar, of Chelsea and Newcastle United respectively, have been placed on Barcelona's shortlist.
Neither player is regarded as a first-choice option at their current club, something which may play into Barcelona's favour if they attempt to negotiate a loan deal.
The report adds that Manchester City are not prepared to sell Eric Garcia, a long-term target of the La Liga side.
