Liverpool playmaker Philippe Coutinho has been tipped to swap Anfield for the Camp Nou, especially in the Spanish press, but according to German daily Bild, Barca are targeting a Bundesliga star instead.
Now that the deal is done, attention is turning to how the Catalans react.
As for Dembele, although Borussia Dortmund are standing firm, MD believes the Germans are coming to terms with the winger's departure, "little by little".
His best season for the club came in 2014-15, where he scored 39 goals, and helped the club in clinching La Liga title. He would have no problem slotting into the 4-3-3 set-up and would bring the kind of excitement on the ball that made Neymar such a Camp Nou favourite.
That's not all. Many fans believed that Barca's 'More Than A Club' motto was sacrificed for commercial reasons in a recently expired shirt sponsorship with Qatar Airways, and there is ongoing concern that the supply of youth talent from the famed 'La Masia' academy system has dried up. What's more, with his contract expiring in a year, the Gunners need to cash in now or risk losing him for nothing in 2018.More news: More rain forecast for New Orleans Metro area Sunday
Neymar, Messi, Suarez - were the heart of Barca's success, and the key to keeping Messi happy was keeping him surrounded with his fellow stars. So much so, in fact, that when asked in Miami last week if he is 100 percent staying at Juventus, Dybala said: "You'll have to ask the club". Much was made of a reported bust-up at half-time of the Champions League final during which Bonucci supposedly criticised Dybala for pulling out challenges after being booked early on. Alvaro Morata and Pogba did the same in 2016.
Mbappe could well cost north of €100m, but it would be an investment worth making for an 18-year-old who can play anywhere across the front line to devastating effect.
Barca have already lost a gem in Jordi Mboula to Monaco, but there are others in Gerard Lopez's squad who could be worth a gamble.
Perhaps another sign could have come even earlier when Neymar finished third in the race for a coveted Ballon d'Or two years ago-a prize ultimately given to his teammate, Messi, who's now won four of them, in addition to earning a nomination for a further two.
