Barcelona boss Ronald Koeman has submitted a four-player shortlist the club must sign in the next four weeks before the close of the transfer window.
The players included Liverpool midfielder Georginio Wijnaldum, Inter’s central defender Stefan de Vrij and Olympique Lyonnais forward Memphis Depay.
It is claimed that Manchester City defender Eric Garcia, who came through the Blaugrana’s youth academy, is the other player who has been identified by Koeman.
Memphis, Wijnaldum and Garcia are all players who are entering the final year of their respective contracts, meaning that all three of their parent clubs are likely to consider a sale at a reduced market price.
Juventus midfielder Miralem Pjanic is the only confirmed arrival at the Camp Nou so far this summer – although young forwards Pedri and Francisco Trincao have joined from Las Palmas and Braga respectively – with midfielders Arthur Melo and Ivan Rakitic among those who have left the club.
