The Tottenham Hotspur manager produced a masterstroke with the summer signing last week.
If there is, Tottenham haven't yet found him - or he may cost billions.
For everything about the South Korean's start to his White Hart Lane career screams Pochettino. That's not to go overboard and suggest the 23-year-old is the best player the north London side will ever see.
But he's an ideal fit for the current Tottenham manager, with his approach to the game exactly what the Argentine wants and demands from his players.
For starters, he's the right age. It's his energy levels, though, that make him the perfect Pochettino player. He could run forever based on the Crystal Palace game alone.
And the Spurs head coach is already managing Son brilliantly - as last week's little masterstroke proves.
Indeed, what was impressive about how Poch managed the South Korean was his decision to play him up top in the Europa League and bring him back to the no.10 role v Palace.
Against Qarabag, the centre-forward position was perfect for the 23-year-old. He had space, received plenty of service and, ultimately, grabbed two goals. That did wonders for his confidence.
On Sunday afternoon, he wouldn't have received as much joy as a no.9 against a Premier League side. But he didn't need to. Fresh off his European brace, Son was bursting with energy and looked far sharper than during his debut against Sunderland.
With many others, it might not have worked. But the Tottenham signing can run forever - something Pochettino will absolutely love.
