Diego Forlán
In June 2010, Costa returned to the "Colchoneros", initially as a backup to Sergio Agüero and Diego Forlán – Atlético also paid an undisclosed sum to Braga to buy all the residual 30% economic rights (the former also had to pay in excess of €833,000 in agent's fees to Gestifute). He was an unused substitute as Atlético won the 2010 UEFA Super Cup on 27 August.
