Portugal coach Paulo Bento says morale in the camp remains high amid the fallout from his side's disappointing goalless draw with Macedonia in their UEFA EURO 2012 warm-up last weekend. Angry home fans greeted the final whistle of Saturday's listless outing in Lisbon with boos and whistles, the result marking the second game in succession that Portugal had failed to find the net following February's stalemate with Poland. The barren run has raised question marks over Portugal's chances heading to Poland and Ukraine, particularly given the strength of their group-stage opponents - Germany, the Netherlands and Denmark. Bento's side contest their final warm-up against Turkey tomorrow, and the coach is confident his players will prove their worth. "There were no problems with players' attitude and that makes us calm," Bento told reporters. "We will try harder tomorrow, knowing that Turkey will play differently. "We want to improve every game, we want to win," he said. "I am an optimist by nature but there is concern for the game with Macedonia. Tomorrow we will have a different game, we want to win and therefore we have to score." Bento has meanwhile rubbished claims that Portugal's EURO hopes rest solely with Cristiano Ronaldo, who is coming off the back of a stellar title-winning season with Real Madrid. "We're not putting pressure on him to solve all our problems, but we hope he'll help us to solve some of them," Bento said. "We want a team that plays well. We don't want Ronaldo to have to do everything."
