Diego Costa insisted Atletico Madrid are capable of defeating anyone with their desire and courage after upstaging Real Madrid in the UEFA Super Cup.
A brace from Costa saw Atletico to a 4-2 extra-time victory against Champions League holders and city rivals Madrid in Tallinn on Wednesday.
Costa scored the fastest ever Super Cup goal after just 49 seconds in sensational fashion midweek before Karim Benzema equalised 26 minutes later and Sergio Ramos' penalty put Madrid ahead with 29 minutes remaining in the Estonian capital.
Europa League champions Atletico, however, were not done as Costa struck again 16 minutes later to force extra time, where Saul Niguez's stunner and Koke's sealer clinched a seventh title for head coach Diego Simeone.
