Recording his first win of the season, Perez was warmly embraced by Red Bull personnel, family and friends after the chequered flag, but Verstappen senior looked on in stony-faced silence.
That was captured on camera, with many Formula 1 fans on social media saying the reaction was 'rude' and 'unsportsmanlike' while some even referred to the ex-Arrows and Minardi driver as a 'sore loser.'
Here's a sample of how F1 Twitter reacted to Jos Verstappen snubbing of Sergio Perez:
Jos Verstappen blanking Checo while all around him celebrate - how rude and unsportsmanlike. I know they have differences but to not congratulate him is petulant and not what #F1 is about - a really poor example to set to younger generations.
