Cape Verde boss Bubista targets place in knockout stages after draw with Uruguay
"Considering what we've done with two international-grade teams, I think our focus has to be qualifying," said the 56-year-old former Cape Verde international.
"If we were to think about the knockout rounds, I think it's only legitimate to do so considering what we've done."
Kevin Pina scored his country's first goal at a World Cup tournament with a free-kick from 30 metres mid way through the first half.
Maximiliano Araujo levelled for Uruguay after 44 minutes and the Sporting Portugal midfielder set up Agustín Canobbio to give Uruguay the lead in first half stoppage time.
But Cape Verde responded with a strike just after the hour mark from Helio Varela.
