Lille OSC is lining up another major defensive move: the club has opened talks with FC Sevilla to sign Tanguy Nianzou, a former PSG product. While the Dogues sit 3rd in Ligue 1 with 61 points (18W‑7D‑9L) and a recent LWDWD run, the signing could shore up a back line thinned by the exits of Aïssa Mandi and Chancel Mbemba.

Who is Tanguy Nianzou and why is he attracting interest?

Nianzou, 24, grew up in the PSG academy before stints at Bayern Munich and Sevilla in 2022. Despite training at top clubs, he has logged only 12 Liga appearances this season, 648 minutes, with five yellow cards and one red. His contract runs until 2027, yet Sevilla struggles to justify the original €16 M fee.

What could Lille OSC gain?

Signing a defender who has already featured for Bayern and PSG gives Lille a rare profile: international experience and untapped potential. The club has already spent nearly €15 M on Basar Önal, bolstering its squad. A 24‑year‑old still under contract could be sold for profit if form returns, adding a valuable financial lever.

What risks does the transfer carry?

The biggest concern is Nianzou’s injury record. Recurrent setbacks have limited his playing time, and his inconsistency worries analysts. Moreover, the asking price remains steep for a player who has not proven himself in La Liga. Lille must weigh the immediate outlay against medium‑term upside.

What’s likely to happen next?

Negotiations between the clubs are reportedly advanced, according to Le Petit Lillois. If Sevilla agrees to release the defender, Lille could seal the deal before the summer window closes, giving the manager an extra option for the upcoming campaign. The club will still need to balance the budget already committed to Önal to avoid jeopardising other transfer plans.

In short, Lille OSC is placing a bold bet: turning an injury‑prone talent into a defensive cornerstone while staying a challenger, 15 points behind league leaders Paris Saint‑Germain.
