Vergne wearing Indy 500 rookie Alesi’s helmet

Jean-Eric Vergne will race formula one veteran Jean Alesi’s helmet design this weekend in Monaco.

It is Vergne’s tribute to his French countryman as former Ferrari and Sauber driver Alesi, 47, this weekend becomes the oldest ever rookie in the Indy 500.

Vergne, 22, had planned to watch Alesi from Indianapolis’ fabled stands, "but then came the news I was driving for Toro Rosso and of course that meant a clash with Monaco".

Alesi starts the Indy 500 from 33rd and last, with the vastly-underpowered Lotus engine.
