Manchester United have reportedly emerged as frontrunners to sign RB Leipzig’s Castello Lukeba this summer, leapfrogging Arsenal in the race for the highly-rated French defender, according to Spanish outlet Fichajes.
Why United Need Him Badly
Signing a left-footed centre-back has become an absolute priority at Old Trafford — and it’s easy to see why. Lisandro Martínez’s injury record continues to haunt the club, while young Ayden Heaven has found himself on the periphery under interim manager Michael Carrick. Harry Maguire has plugged the gap, even earning a short-term contract extension, but nobody genuinely believes that’s a long-term solution.

Lukeba, 23, offers something United’s backline has desperately lacked: composure in possession and genuine defensive reliability.
The £50m Deal Leipzig Are Willing to Strike
The Bundesliga side need to balance the books this summer and are prepared to let Lukeba leave — despite his £70m release clause running until 2029. Reports suggest Leipzig would accept closer to £50m, and United are already assembling a formal bid.
Arsenal have monitored the defender closely, and Bayern Munich briefly entered the picture — but neither has matched United’s reported urgency.
The Risk Factor
It’s not all straightforward. Lukeba has dealt with fitness concerns of his own, which any potential buyer must weigh carefully. Sound familiar? United’s recent centre-back history is littered with injury gambles.
