New Barcelona coach Luis Enrique has vowed to build a side who will "excite" supporters but warns that they must iron out their defensive weaknesses next season.
The 44-year-old was appointed as Gerardo Martino's replacement on Monday and signed a two-year deal after leaving Celta Vigo.
Enrique's return extends his association with the club, having represented them as a player for eight years before a stint in charge of the club's B team.
The former midfielder intends to implement his own attacking style but added that he wants to strike a balance between their offensive threat and rearguard resilience.
"Today is a very exciting day for me, a very special day, a day we start to build a new Barca, a Barca that can excite people," he told reporters.
"I am very happy to be here. The new season begins here, we've got things to decide. I am hoping we have got a great season ahead but I know I have got a big task ahead of me.
"I am more than a manager, I am a leader, I am here to lead. Leadership skills are very important.
"Attacking football is what Barca identifies with, that's what we play, what people have fallen in love with but we need to defend well too.
"Obviously I will bring things to the team because I have got my own ideas but I am hoping for an attractive and effective Barcelona."
