The 2017-18 AC Milan season was one that saw a lot of drama and controversy, but it also had some exciting moments. The team had a strong start to the season, finishing second in Serie A and qualifying for the Champions League, but then faced a difficult period in the summer transfer window.

Matteo Gabbia played a key role in this period, becoming one of the most important players for the club. He scored two goals in just five games, which helped AC Milan secure their place in the Champions League group stage, where they faced Manchester United. However, Gabbia struggled to make an impact at the club, scoring only once in eight appearances during the season.

In addition to Gabbia, AC Milan also suffered from injuries throughout the season. Mario Balotelli missed most of the season due to injury, while Alessandro Del Piero and Silvano Murci were unable to play due to personal reasons. Despite these setbacks, AC Milan still managed to finish the season with a good record, reaching the quarterfinals of the UEFA Europa League.

Overall, the 2017-18 AC Milan season was a mixed bag, with both positive and negative aspects. While they made some exciting runs and made some good signings, they also faced some tough challenges and had some struggles off the pitch. Despite these challenges, AC Milan still managed to achieve some success, especially with Gabbia's contributions to the team.
