Manchester United player of the month for April Ander Herrera and Manchester City playmaker David Silva are "dreaming" of a return to La Liga to play for Barcelona, reports in Spain claim.
Even though the Catalans are banned by Fifa from making any additions this summer, the club's officials are already planning for the future in order to bolster the squad in the next January transfer window.
Barcelona recently appointed former AC Milan sporting director Ariedo Braida to prepare the overhaul following the sacking of Andoni Zubizarreta in January.
After the Catalans signed Neymar and Luis Suarez during the last two summer transfer windows to partner Lionel Messi up front, Braida has earmarked the signing of a top midfielder to replace Xavi Hernandez as the top priority.
Juventus star Paul Pogba is said to be on the top of his shopping list but Sport claims that with Chelsea, Paris Saint-Germain and City also interested, Barcelona are considering other alternatives.
And the Catalan newspaper claims Herrera and Silva are among the alternatives as the Spanish duo want to move to the Camp Nou.
Sport claims City are expected to make a huge summer clear-out and Silva may be available for a reasonable price.
Meanwhile, the report points out Herrera has been flirting with a move to the Catalans since Pep Guardiola's tenure in La Liga.
In the summer of 2014, Barcelona reportedly considered his signing but with Athletic Bilbao refusing to accept anything below his €36m (£26m, $40m) release clause, the Catalans opted instead to sign former Sevilla midfielder Ivan Rakitic.
But it looks unlikely that United will want to negotiate his departure, with the Spaniard recently becoming a key player for manager Louis van Gaal, earning praise from Paul Scholes and being named the club's player of the month on two occasions this season.
