Reliable sources are reporting that discussions have begun between Mainz and NEC Nijmegen over the transfer of Kodai Sano. The midfielder has emerged as a top target for the interested team, and talks are reportedly progressing as the two clubs explore whether there is a deal to be done for the player. Feyenoord, Ajax and PSV Eindhoven remain in the background, but for now, Mainz are leading the way in ongoing talks. Mainz are only scoring 1.15 goals per game (23 in 20) this season, which suggests they need more creativity in the middle. Kodai Sano would be seen as the link to raise the tempo and feed the attack. NEC Nijmegen have also been linked with Willum Thor Willumsson, Isak Hansen-Aaroen and Danilo while Mainz are reportedly monitoring Otto Ruoppi. More on this story as it develops.
