The Globo article just mentions it's only talks though and any deal for Paulinho would be difficult as Guangzhou Evergrande, have no plans on selling him.
I wonder who else Raul Sanllehí talked with down in Brazil. So far the names that have shown up are Vitinho,Lima and Paulinho. But out of the three the only one that truly has concrete backing(Rumor wise) is Vitinho, who would be a signing for the B team with potential first team prospects.
Why is Paulinho even an option
