High precision measurements of B meson decays offer some of the most powerful tests of the Standard Model paradigm. They thus allow us to indirectly search for manifestations of physics beyond the SM, up to energy scales well exceeding the direct searches at the Large Hadron Collider. Over the past years some puzzling tensions have appeared between the experimental measurements and the theoretical predictions for B meson decays into final states including leptons, which may point to a violation of lepton flavour universality, forbidden in the SM. Although the precision on the individual measurements does not yet allow us to differentiate between mere statistical fluctuations and actual deviations from the SM, together these tensions suggest a different story. In this talk I will discuss the latest results from the LHCb experiment regarding these anomalies and illustrate that they might very well be our first hints for physics beyond the SM.
