Barcelona are eyeing Olympique Lyon fullback Malo Gusto.
L'Équipe says both Barça and Manchester United are interested in the player.
Only 19 years of age, he is among the most promising full-backs in the competition. Barça, however, would find a tough negotiator in Jean-Michel Aulas, head of Lyon.
The player is unlikely to leave for less than €40m.
Barca are also being linked with PSG's former Real Madrid defender Achraf Hakimi.
PSG signed Achraf a year ago for a fee of around €70m with variables, and he signed until 2026. Before that, Inter signed him from Real Madrid for €45m.
