Gretas should soon be joined by Juan Manuel Iturbe, a member of the Argentine youth (up to 20 years old) national team.
The 17-year-old footballer, already dubbed as the "new Messi", left "Cerro Porteno" in the summer and moved to "Quilmes", but could not debut for the new team due to a conflict between the clubs.
"Porto" has already reached an agreement with "Cerro Porteno", so the 1.5 million euro deal should happen in the near future.
