We solve the Faddeev equations for the two meson-one baryon system ππN and coupled channels using the experimental two-body t-matrices for the πN interaction as input and unitary chiral dynamics to describe the interaction between the rest of coupled channels. In addition to the N∗(1710) obtained before with the ππN channel, we obtain, for Jπ=1/2+ and total isospin of the three-body system I=1/2, a resonance peak whose mass is around 2080 MeV and width of 54 MeV, while for I=3/2 we find a peak around 2126 MeV and 42 MeV of width. These two resonances can be identified with the N∗(2100) and the Δ(1910), respectively. We obtain another peak in the isospin 1/2 configuration, around 1920 MeV which can be interpreted as a resonance in the Na0(980) and Nf0(980) systems.
