De Telegraaf says the offer went in on Wednesday and is worth an initial 20 million euros with five million more in variables. Barça are convinced they will reach an agreement to sign Dest in the coming hours.
Barça's offer is superior to the one made by Bayern Munich, the other team keen on Dest. Barça have sold Nelson Semedo to Wolves and will use the money to try and sign Dest.
Semedo left for 30 million with 10 million more in possible add-ons. Dest, 19, will arrive for less and has his whole career ahead of him.
