The masses of the recently reported by LHCb two pentaquark charmonium states$P_{c}^{*}(4380)$ and $P_{c}^{*}(4450)$ which are supposed to have theconfiguration $(uudc\overline{c})$ have been estimated in the framework of thequasiparticle model of diquarks considering $[ud][uc]\overline{c}$configuration. The masses are reproduced very well which indicates that thedescription of diquark as quasiparticle is very useful for describingmultiquark state and to understand the dynamics of it.
