Costa Rica will switch to a more aggressive style when it plays Ecuador on Thursday.
In an effort to stay alive in Group A after its 4-2 loss to Germany in the opening match of the World Cup, the change also compensates for the loss of defender Gilberto Martinez, who left because of tendinitis in his left leg.
"These situations force us to a change, and we are already analyzing what to do," Costa Rica coach Alexandre Guimaraes said Saturday.
The coach said his plan against Ecuador is mainly "strengthening our attack," especially after Ecuador upset Poland 2-0.
Striker Paulo Wanchope, who scored both goals against Germany, agreed that a "more aggressive" strategy is needed against Ecuador.
"We have to be more on the offensive and seek the victory from the very beginning," Wanchope said.
He said the team also needs to find a formula to gain more possession of the ball, and he expects more support.
"The greater confidence we have gained in recent days will help us to get a much needed victory," Wanchope added.
The Costa Ricans returned from Munich and the players rested for several hours. Full training will resume Sunday, reports AP.
