  Flavour physics is currently well described by the Standard Model except for
some measurements which could be signalling new physics. We briefly summarize
the status of tensions in rare exclusive semi-leptonic $B$ decays and in
$R_{K/D^{(\ast)}}$ ratios. We also address the issue of the long standing
tension in the $|V_{cb}|$ and $|V_{ub}|$ exclusive/inclusive determinations.
