Barcelona are pushing to sell four players this week.
Barca want the sales completed before the squad departs on Wednesday for their US preseason tour.
Clement Lenglet, Alex Collado, Franck Kessie and Sergino Dest are all being pushed to leave, says Sport.
Lenglet spent last season on-loan with Tottenham, Collado was with Elche and Dest with AC Milan.
Kessie, meanwhile, joined Barca last summer from AC Milan.
