Barcelona reportedly recently held secret talks with agent Mino Raiola to discuss possible deals for Borussia Dortmund's Erling Braut Haaland and Ajax's Noussair Mazraoui.
Haaland is widely expected to leave BVB during this summer's transfer window, with the Norway international set to have a £63m release clause in his contract ahead of next season.
Mazraoui, meanwhile, will see his Ajax contract expire at the end of June, and the Morocco international is expected to leave his Dutch club on a free transfer in search of pastures new.
According to De Telegraaf, Barcelona president Joan Laporta and sporting advisor Jordi Cruyff were recently in Monaco to meet with Raiola to discuss deals for his clients.
Haaland - also linked with Real Madrid, Manchester City and Paris Saint-Germain - has scored 23 goals and registered six assists in 20 appearances at club level this season.
Meanwhile, Mazraoui has featured on 27 occasions for his Dutch side during the 2021-22 campaign, contributing five goals and four assists in the process.
