Liverpool splashed out £60m to land the 20 year-old from Rennes, where he will spent the rest of the season on-loan.
Jacquet will join Liverpool over the summer, having signed a contract to 2031.
French football expert Julien Laurens told BBC Sport: "It's a lot of money but Jacquet has everything to become one of the best centre-backs in the world in the next few years.
"He is arguably the best centre-back of his generation.
"He's quite tall, quick and strong - and he's a machine when it comes to duels in the air and on the ground. He reads the game well and is good on the ball.
"He's not a proper ball-playing centre-back yet. Technically, there is a lot to improve on, but he's a smart kid and he can get there and become like a Virgil van Dijk."
He added, "It won't be easy to step up from Ligue 1 to the Premier League at a club like Liverpool.
"It wasn't easy for Leny Yoro and it wasn't easy for William Saliba at the beginning too, but Jacquet is so so talented."
