Mainz 05 secured their first win of the season on Saturday evening as they defeated Borussia Mönchengladbach 2-1 at the Commerzbank-Arena. The victory was Lee Jae-sung's second goal of the campaign after his brace against VfB Stuttgart.

Barreiro also played a key role in the match, scoring his first goal since joining the club from Getafe CF last summer. The Brazilian midfielder scored the equalizer in the 77th minute to level the scores at 1-1.

The victory helped Mainz move up to 16th place in the Bundesliga table, just one point behind their relegation rivals. The team now faces a crucial game against Union Berlin next weekend, with only three points separating them from the bottom four teams.

"Lee Jae-sung and Barreiro have been instrumental in our recent performances," said coach Frank Rijkaard. "Their goals were vital in helping us secure all three points against Gladbach."

The result has boosted the morale of the team, who will be hoping to continue their good form against Union Berlin. However, it is clear that there is still work to be done if Mainz want to avoid the drop this season.

Despite the tough challenges ahead, Mainz remain determined to fight for survival and finish the season on a high note. With the support of their fans, the team will undoubtedly give their best effort to achieve their goal.
