The measurement of the magnitude of the Vcb element of the Cabibbo-Kobayashi-Maskawa matrix is of great importance in the validation of the Standard Model (SM) of particle physics. The current world averages for the inclusive and exclusive measurements of $|V_{cb}|$ are approximately three standard deviations apart, representing a long-standing puzzle in flavour physics. In this work we present the measurement of $|V_{cb}|$ using semileptonic Bs decays produced in proton-proton collision data collected with the LHCb detector during the Run1 of the LHC. This is the first determination of $|V_{cb}|$ from exclusive decays at a hadron collider and the first using decays of the Bs meson.
