Barcelona defender Dani Alves has warned his side against complacency when they host a Paris Saint-Germain side bolstered by the return of key personnel through suspension to the Camp Nou tomorrow.
Two goals from Luis Suarez took Barca to the brink of a seventh Champions League semi-final in eight seasons as they romped to a 3-1 win in the first-leg of the quarter-final tie in Paris last week.
However, a late own goal from Jeremy Mathieu offered the French champions a glimmer of hope as they welcome back top-scorer Zlatan Ibrahimovic and midfield maestro Marco Verratti.
"We will not speculate with the result because we don't know how to," Alves, who has been linked with a move to PSG come the end of the season, told Barca's website.
"The philosophy and the spirit of the team is to challenge for every ball as if it was the last.
"We cannot think about our advantage, but just control the game and look to score from the first minute. That is the only way to overcome PSG."
Barca remained on course for a treble of La Liga, Copa del Rey and Champions League with a hard-fought 2-0 win over Valencia on Saturday thanks to goals in the first and last minute from Suarez and Lionel Messi, who registered his 400th goal for the club.
And Luis Enrique's men will also have key players back available as Alves returns after he too missed the first-leg through suspension, whilst Andres Iniesta is expected to overcome the back bruising he suffered at the Parc des Princes in time to feature.
