Barcelona sports chief Andoni Zubizarreta has welcomed back coach Tito Vilanova.
It is not yet known if Vilanova will return to the bench for Tuesday's first-leg meeting with PSG, but the 44-year-old did travel with the Barca squad to Paris.
Vilanova's last away match with Barca was against Real Sociedad on January 19.
Zubizarreta told reporters at the airport prior to Barca's departure "The presence of Tito marks the return to normality.
"That Tito is with us is a good sign, without doubt. He's well and therefore he's travelling."
