Botafogo are ready to sell talented defender Doria to Europe this summer.
Doria captained Brazil at the Toulon tournament and was scouted by Arsenal, Manchester United and Manchester City over the past year.
The young defender is inside the final year of his contract, which has seen Botafogo begin circulating his name to European clubs.
Galatasaray had a €10 million offer turned down last week, with Botafogo seeking €15 million for the youngster.
Along with United, City and Arsenal, Doria is also on the radars of Real Madrid and Barcelona.
