Atletico Madrid president Enrique Cerezo is hopeful of concluding a deal for Lanus forward Eduardo Salvio in the next few days.
Atletico are looking to make the highly-rated Argentinian their second - and possibly final - signing of the January transfer window having last week brought in midfielder Tiago on loan from Juventus for the remainder of the season.
Reports in Spain suggest the 19-year-old Salvio could cost Atletico in the region of €8million.
Cerezo said: ``I hope that Salvio will be the next reinforcement. The negotiations are going well and I hope that his signing can be finalised in the coming days.
``With the arrival of Tiago and Salvio, in principle the winter market will be closed for us. I think that both players can contribute goals, in addition to those already in the squad.''
Portugal international Tiago had due to be presented on Monday but has had to remain in Turin due to bad weather.
