Barcelona are reportedly keeping tabs on Paul Pogba, Adrien Rabiot and Frenkie de Jong ahead of next summer.
The La Liga champions were linked with a move for Pogba over the summer, with Sky Sports News claiming that Barca offered £45m plus Yerry Mina and Andre Gomes for the World Cup winner.
Rabiot has been a key part of Thomas Tuchel's midfield at Paris Saint-Germain, while De Jong helped Ajax to the Europa League final last year.
According to Sport, Barca want to sign two out of the three players to bolster their midfield next year.
The report adds that chairman Maria Bartomeu displayed an interest in the trio earlier this summer, but none of the three clubs would sanction a deal.
