Lille have invested a chunk of the €80 million (£73.6m/$89.5m) they received for Nicolas Pepe by signing Turkey midfielder Yusuf Yazici from Trabzonspor for €16.5 million (£15.2m/$18.5m).
After securing a huge fee from Arsenal for Pepe last week, the Ligue 1 club are well-equipped to bolster their squad and 22-year-old Yazici has joined on a five-year deal.
Trabzonspor announced on their website that Lille would initially pay €16.5 million for the full international, plus a further €1m after he plays 25 games for the French club. Lille defender Edgar Ie also moves to Trabzonspor as part of the deal.
