In the front field, Seedorf, Ibrahimović, and Robinho are Allegri's top choices. Although Seedorf is a bit tired, the already marginalized Ronaldinho under Allegri will find it difficult to get an opportunity in such a crucial Champions League match. Currently, AC Milan has 5 points in the group stage, Auxerre and Ajax both have 4 points. Since Auxerre will face Real Madrid away in the last round of group matches, in order to seize the final chance for advancing, they must strive for victory at home, and AC Milan will also face a severe test.
Antonini surprisingly did not play in the match against Fiorentina. According to reports, Antonini suffered a minor muscle strain during the last warm-up before the game. Despite being a slight injury, this not only prevented him from playing against Fiorentina, but he is also unlikely to start in Tuesday's match against Auxerre. In the match against Fiorentina, Bonera appeared as the starting right back, replacing the red-card suspended Abate. In this match, Abate should be able to return to the starting lineup, but Allegri is unlikely to choose Bonera to play as the left back. Veteran Zambrotta may face the challenge of playing two games in three days, and his condition was already quite fatigued in the rain-soaked match against Fiorentina.
In the defensive midfield position, Pirlo's injury has still not healed. Compared with Antonini, he is almost certainly out of the question for the match against Auxerre. Fortunately, in recent times, even without Pirlo starting, the "muscle-type midfield" composed of Ambrosini, Gattuso, Flamini, and Boateng in various combinations of three has performed quite well. From the perspective of Pirlo's safe recovery and maintaining squad stability, there is no objection to Allegri continuing with the same midfield that played against Fiorentina. The only question is whether Boateng, who performed excellently as a substitute, might rotate into the starting lineup in place of either Gattuso or Flamini.
On Tuesday evening local time in Italy, AC Milan will play an away match against Auxerre in the Champions League group stage, which will be a key match for AC Milan. However, bad news came before the match: AC Milan currently has many injured players, and both Pirlo and Antonini are likely to miss this game.
