Colombia striker Jackson Martinez says that his side were delighted to finish at the top of Group C at the World Cup, but are now fully focused on their next game against Uruguay.
The South American team finished the group stage on nine points after taking three wins from their three games. They beat Japan 4-1 in their final match of the first round, after impressive victories over Greece and the Ivory Coast.
Now Martinez is looking ahead to the round-of-16 clash against Uruguay.
"With much joy I cannot deny that we are very happy about the achievement, but already automatically thinking about the next match," the Porto striker said.
He added: "We know we have done some great work but we need to keep going. We are focused on getting ready for that next match against Uruguay."
Martinez, who has been linked to Arsenal and Chelsea this summer, was handed a start up front for Colombia against Japan after beginning the two previous games on the substitutes' bench.
He responded with two goals in an excellent all-round performance and will hope to be rewarded with a starting berth in the next round.
With star striker Radamel Falcao missing the World Cup through injury, Martinez was tipped to step into a starring role in the tournament after a good domestic season for Porto. The Japan game could be a sign of things to come for the 27-year-old.
Colombia captain Mario Yepes, meanwhile, says that his side are expecting a tough test against Uruguay, who qualified second from Group D ahead of England and Italy.
"It is going to be a difficult match, very difficult, because we have had the opportunity of watching Uruguay's matches during the World Cup, and we have seen that they are a good side - a team that defends well, that has a good work ethic," he said.
He added: "We need to be ready to strengthen, play a good match, and show a good game like we have in the group stage."
