(CNN) -- Brazil announced their arrival at this year's Copa America tournament in Argentina Sunday with a disappointing goal-less draw against Venezuela.

The nine-time champions missed a number of good opportunities in a match they dominated for long spells, including a fierce shot from Milan's Alexandre Pato which struck the bar on 38 minutes.

They were also denied what looked to be a clear penalty minutes later, when defender Oswaldo Vizcarrondo appeared to handle the ball in his own box as he slipped trying to block a shot on the rebound from Robinho.

Venezuela, whose national sport is actually baseball, improved after the interval but they failed to really threaten Julio Cesar in the Brazilian goal.

I think that it is incredible that all the good teams could not score and the not so good teams are holding the good teams I think that is a great opportunity to venezuela or other team to win the copa America I really hope that the good teams like brasil and Argentina rise up again and win the other matches.
