Ajax defender Noussair Mazraoui could arrive in Barcelona next month.
Off contract in June, Mazraoui has told agent Mino Raiola he's ready to agree pre-contract terms with Barca with the aim of arriving in June.
However, AS says the defender could join Barca immediately in a straight swap for Sergino Dest.
Barca are willing to sell Dest and could send him back to Ajax in a swap for Mazraoui.
It's suggested Barca would insist on a cash component be included by Ajax as part of the exchange.
