Ozan Kabak and Conor Gallagher are expected at Crystal Palace this week.
The Sun says Palace are in talks with Turkish centre-half Kabak about a return to the Premier League after his loan spell at Liverpool from German side Schalke.
The Eagles want to thrash out terms quickly and will go back to Lyon in France for Danish defender Joachim Andersen if Kabak is too expensive.
Chelsea midfielder Gallagher, 21, is due to be cleared to go out on loan, with Palace optimistic they can see off Newcastle and a late move from Leeds.
New Eagles boss Patrick Vieira is keen to strengthen his squad as soon as possible.
He has already snapped up Chelsea defender Marc Guehi, 21, on a five-year deal.
