Even Real Madrid had eyes on the player at one point along with Tottenham Hotspur.
Big European clubs are already making moves and one young defender is attracting a lot of attention.
The player is just 22 but has already made a name for himself in Germany.
He spent this summer representing France in the U21 Euros.
The tournament did not go as planned, though.
France crashed out against Germany in a tough 3-0 loss.
It was his final appearance with the U21s, but he wore the shirt with pride.
That match also marked the end of a chapter. What comes next could be even more exciting.
This defender made his name at Lyon before moving to the Bundesliga.
Since joining his current club in 2023, he has taken major steps forward.
He even stepped in to replace a key starter who had left for Manchester City.
Despite a short spell out with injury last season, he returned stronger.
He ended the season with over 30 appearances.
His calmness, speed, and maturity stood out.
Even Real Madrid had eyes on him at one point.
RB Leipzig gave him a new contract last autumn. That deal runs until 2029.
But clubs know that may not stop a transfer.
Now, according to Foot Mercato, Liverpool and Bayern Munich are leading the race for Castello Lukeba.
They are joined by Tottenham Hotspur, but the main fight looks to be between the Reds and the Bavarians.
His release clause is set at €90 million, but Leipzig are ready to negotiate.
The player himself is also open to a move.
Liverpool are currently prioritizing a move for Crystal Palace defender Marc Guehi.
So, if their pursuit of the English international fails, then Liverpool could pursue Castello Lukeba with stronger intent.
Liverpool has already beaten Bayern Munich in a transfer race this season with Florian Wirtz.
Another race between the two clubs is on.
And it looks like one of Europe’s top young defenders could be on the move very soon.
