When Mercedes' drivers bid farewell to their boss in style

The Spanish Grand Prix held on this day in 2019 marked the last race for Dieter Zetsche as the head of Mercedes-Benz, and Lewis Hamilton and Valtteri Bottas - sporting a fluffy Zetsche 'stache - were given a special photo-op with their boss in Barcelona

The long-serving Daimler CEO stepped down from his management positions at the group on May 22 and ceded the lead baton to his successor, Ola Kallenius.

A strong supporter of Mercedes' involvement in Grand Prix racing, Zetsche's enthusiasm, guidance and backing were instrumental from the outset and a vital ingredient in the manufacturer's successive world Constructors' titles.
