DC United officials are in La Plata this weekend for talks with former Inter Milan and Lazio star Juan Sebastian Veron about a move to MLS next season.
Controcampo says DC United's offer is for around £15 million to the Argentina international midfielder, who regularly spends his offseason in Miami.
Ex-Chelsea and Manchester United schemer Veron is expected to accept the switch, which could see Diego Simeone also quit Estudiantes as coach.
