It looked like being another one of those afternoons in favour of Lewis Hamilton. Ones we have all been grown accustomed to now.
He led into the first corner of the Italian Grand Prix, and his only realistic challenger in Mercedes team-mate Valtteri Bottas had suffered a poor start and dropped places from second.
Anyone who has watched Formula One for the past six years of heavy Mercedes domination will by now know this kind of scenario a vast majority of the time leads to a straight forward victory for the world champion.
Lewis Hamilton looked on course for a straight forward win at the Italian Grand Prix
But after suffering a pit-stop fiasco he picked up a penalty effectively dropping him to last
Except F1 can work in mysterious ways and when you least expect it. An accident or retirement anywhere on the track can have implications all through the field up to and including a dominating race leader.
Around 19 laps into the race, Hamilton was cruising with an advantage of over 10 seconds, but Kevin Magnussen's retirement for Haas around the pit-stop window threw what was turning into another processional F1 weekend into total chaos when the safety car was brought out.
Unfortunately for Hamilton, luck was simply against him. His track position meant his team had mere seconds to react in whether to bring him in for a pit-stop or risk staying out and losing out in strategy.

His crash came before Hamilton had a chance to serve his stop/go penalty punishment
In doing so clear instructions heading into the final parabolica corner warning drivers not to pit in with a red 'x' on digital boards were ignored or missed.
From the moment Hamilton then entered the pit-lane, his race was doomed.
After an investigation, he was given a 10-second stop/go penalty which is the harshest in-race punishment a driver can receive. He wasn't the only one to suffer the fate, with Alfa Romeo's Antonio Giovinazzi doing the same and collecting the penalty.
