Several groups of Mainz players stood in front of fans and took selfies, and Lee Jae-sung took pictures of the players and fans with his cell phone. Mainz shared the status of the team with the photos on social media, saying, "The tension is rising toward the season."

Lee Jae-sung was the hero who saved Mainz from the relegation zone last season. Mainz struggled throughout the last season, staying in the relegation zone. Then, in the 33rd round at home to Dortmund, Lee Jae-sung scored multiple goals and emerged from the relegation zone with a 3-0 victory. Mainz settled 13th in the league with a final draw. Lee Jae-sung scored six goals in 31 games in his third season at Mainz.

Lee Jae-sung is calmly preparing for the 2024-25 season. He started as a second-line striker in a preseason game against Montpellier on the 10th, helping his team win 3-1.

Mainz freshman Sano seems to have settled down quickly despite controversy over sexual assault. Sano also started as a third-line defensive midfielder in the match against Montpellier. He is listed alongside No. 7 Lee Jae-seong at No. 6 in uniform.

Sano, who played for Kashima in the Japanese J-League and confirmed his transfer to Mainz early last month, immediately became involved in an unsavory incident. Police arrested him on charges of sexually assaulting a woman in her 30s by conspiring with two other men at a hotel in Tokyo, Japan, on April 14. Upon his release on August 29, Mainz's team announced that "the Tokyo Prosecutors' Office has completed its investigation into Sano." Sano joined Mainz's preseason training from August 1. After his release, Sano said, "I will take the results of my actions seriously, what to do, and I will take it step by step and make efforts to restore trust. I was very sorry." As soon as he joined Mainz, he quickly completed training and games to prepare for the new season.
