Barcelona defender Dani Alves has warned his side against complacency when it hosts a Paris Saint-Germain team bolstered by the return of key personnel from suspension to the Camp Nou on Tuesday.

Two goals from Luis Suarez took Barca to the brink of a seventh Champions League semifinal in eight seasons as it romped to a 3-1 win in the first leg of the quarterfinal tie in Paris last week.

However, a late own goal from Jeremy Mathieu offered the French champion a glimmer of hope as it welcomes back top scorer Zlatan Ibrahimovic and midfield maestro Marco Verratti.
