Despite Barcelona's growing financial concerns, the treble winners will target a host of burgeoning talent in January, including Aymeric Laporte, John Stones and Breel Embolo.
Albert Roge of Sport reported manager Luis Enrique will consider all three starlets as the Blaugrana look towards the next generation of world-class players.
Roge said the Camp Nou club are "working on the ideas" of signing Laporte and Stones as they search for reinforcements in defence and have also been observing teenage talent Embolo, who has been prolific for Basel.
Barca are well stocked in the forward positions, with Lionel Messi, Neymar and Luis Suarez in the starting XI, but are short of depth after the departure of Pedro to Chelsea.
