Ex-Barcelona president Laporta upset seeing Guardiola at Bayern Munich
Laporta is ready to challenge Sandro Rosell at the next Barca presidential elections.
"It's surprising, or ridiculous, to wish to modify a model of success, and seem to be obsessed with destroying everything we build," the 50-year-old said.
"They made it possible for Guardiola to leave, and we have had no appreciation. Conversely, they have gone on to destroy our image."
