The Argentine accidentally let it slip to Football.London in his press conference that Hitchen was at the Merseyside derby at the weekend, which ended 1-0 to Liverpool thanks to a late Divock Origi goal after a Jordan Pickford blunder.
However, Pochettino said his chief scout was there for fun, jokingly claiming "There is maybe a big surprise in January."
But could Hitchen have an in fact been there for business, and who could he have been scouting at Anfield?
Despite his mistake leading to the only goal of the game, Jordan Pickford is an outstanding young goalkeeper, who fits the profile for a modern day number one.
Good with the ball at his feet and brave in his decision making, Pickford fits the profile of a 'keeper Spurs would potentially look at due to their insistence on playing out from the back.
Pickford is a far better passer than current number one Hugo Lloris and, with the Englishman seven years younger than the Frenchman, he is certainly someone Tottenham could be looking at.
Another young Everton Englishman who may be on the radar is Ademola Lookman.
The former Charlton Athletic prospect has only played 14 Premier League games in the last two season and needs to be at a club who value him higher.
Pochettino has a habit of taking homegrown talent under his wing and helping them reach their potential.
Spurs are on the lookout for a wide forward who is aggressive and direct with pace and trickery, and Lookman certainly fits that profile.
Perhaps Hitchen however, could have been there for the red half of Merseyside.
It is imperative Tottenham replace central midfielder Mousa Dembele, who is injury-prone and out of contract at the end of the season.
An ambitious move for new signing Naby Keita may be on the cards.
Keita was highly regarded prior to his big money move to Anfield from German side RB Leipzig and, despite making a positive start to life under Juergen Klopp, he has fallen down the pecking order.
Keita would be the ideal Dembele replacement, as he is an effective dribbler who breaks lines and looks to get his team up the pitch.
However, Keita is a far better passer, and more effective in the final third than Dembele, making a transfer extremely difficult.
However, Pochettino would no doubt like to open the new stadium with a fancy new signing and, if Daniel Levy pays up, Keita could be a surprise option.
There is no question Spurs need to do business in January, and perhaps Pochettino and Hitchen have spotted a potential acquisition from Merseyside.
