Anyone doubting Daniel Ricciardo's sanity in leaving a team on the cusp of resurgence for one mired in the sloughs of mediocrity should re-listen to the Ozzie's Pole Position bellow at last year’s Mexican Grand Prix. Less the fleeting joy of starting the race from the front, the primeval whoop was the exultation of perfect sporting execution delivering the exquisite killer blow (forever denying Verstappen the youngest ever pole position plaudit). 2 years of being on the wrong end of questionable team race tactics never mind Verstappen driving etiquette was enough for the 29 year old to see which way the wind was blowing even if its ungovernable direction led inescapably to Renault. Much as all the talk has been about ramping up investment to accommodate the expectations and abilities of their new superstar surely even his wide-eyed enthusiasm for life will be sorely tested by the – at least in F1 terms - tight-fisted ambitions of Le Regie. Expect slow progress and your ears to pop if Daniel ever gets - and successfully executes - any sort of move on his previous team-mate.
