Making use of a recently proposed formalism, we analyze the composite nature of the P-c(4450) resonance observed by LHCb. We show that the present data suggest that this state is almost entirely made of a chi(c1) and a proton, due to the close proximity to this threshold. This also suppresses the decay modes into other, lighter channels, in our study represented by J/Psi p. We further argue that this is very similar to the case of the scalar meson f(0)(980) which is located closely to the K (K) over bar threshold and has a suppressed decay into the lighter pi pi channel.
