We study the K{Lambda}(1405) configuration of the KK-barN system by considering K{pi}{Sigma} as a coupled channel. We solve the Faddeev equations for these systems and find confirmation of the existence of a new N{sup *} resonance around 1920 MeV, with J{sup {pi}=}1/2{sup +} predicted in a single-channel potential model and also found in a Faddeev calculation as an a{sub 0}(980)N state, with the a{sub 0}(980) generated in the KK-bar, {pi}{eta} interaction.
