We investigate the viability of leptogenesis in models with three heavy right-handed neutrinos, where the charged-lepton and the neutrino Yukawa couplings are the only irreducible sources of lepton-flavour symmetry breaking (minimal lepton flavour violation hypothesis). We show that in this framework a specific type of resonant leptogenesis can be successfully accomplished, whose distinctive feature is the raise of the baryon asymmetry with the mass scale of right-handed neutrinos for M_
