A goalless draw at Camp Nou will be enough for the Catalan giants to reach the Champions League semi-finals as they held PSG to a 2-2 draw in the first leg of their quarter-final tie in France last week.
"I do not think PSG will change their style," he told reporters. "We know them perfectly well and they are dangerous on the counter-attack. We are used to these scenarios and these teams; that will not change our way of playing. We have to win the match and that will guarantee us a semi-final, our sixth successive participation at that stage.
"In some matches we have lacked luck in the last few minutes. We know that and we have tried to find solutions. This season we have had defensive problems and injuries at the back but we have found solutions and replacements. We hope our team are just as good at finding solutions."
Lionel Messi could start for Barcelona after overcoming a hamstring injury he picked up in the first leg.
