Mercedes drivers bid farewell to the boss in style

Today's Spanish Grand Prix marks the last race for Dieter Zetsche as the head of Mercedes-Benz, and Lewis Hamilton and Valtteri Bottas were given a special photo-op with their boss.

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

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

His guidance and patronage will be missed, along with his impressive fluffy puffy 'stache.
