Luis Enrique will welcome his former employers Celta Vigo to the Camp Nou in La Liga.
Enrique coached the Galician for the 2013-14 season, guiding them to a 9th place finish in La Liga.
"It's a great club in terms of facilities for work, small but it has very large values," Enrique said.
Saturday will see the home debut of Luis Suarez, the former Liverpool striker only made his return last week in the Clasico defeat and he made a long awaited impact in the Catalan Supercup with an assist for Gerard Pique's goal.
Luis Enrique said:"He made a difference to the game every minute he played,
"He shows mobility and eagerness, like the rest of the squad."
Celta Vigo are going well under their new coach Eduardo Berizzo and they sit 6th after nine games following a 3-0 triumph over Levante on Friday night.
Joaquin Larrivey, signed from Rayo Vallecano in the summer, scoring a brace to take his tally to six for the season.
Celta have earned plaudits for their attractive style of football in a last couple of years and Berizzo is keen not to change his style to face Barcelona.
“We’ll try to press them and do that as high upfield as we can, but without losing our own identity, which comes from taking ownership of the ball. We have to be faithful to our ideas and consistent with the things we do, if we’re to take ownership of the ball in a stadium where practically nobody manages to do that," Berizzo said.
