Paulo Bento said he won't be changing his tactics as his Portugal team take on the Czech Republic in the quarter-finals on Thursday.
"All of us are trying to hide some aspects of our strategy but one thing that always changes your strategy is a goal," he said.
"That always makes a great difference to a game. We have to try, even in adverse moments, to be loyal to our playing style.
"We have to keep cool minds, stay focussed and tomorrow we'll see what our opponents will bring to the table.
"We have to counter they're strong points and focus on what we do well but that's no different to any other game," Bento added.
