Flavour physics represents one of the most interesting and, at the same time, less understood sector of fundamental interactions. A series of recent results seem to indicate a coherent pattern of deviations from the Standard Model predictions in this sector. I will show how these “anomalies” could naturally be linked to the old, and still open, puzzle of quark and lepton masses, and I will discuss attempts to solve both these problems in terms of physics beyond the Standard Model.
