The Gazzetta dello Sport’s front-page headline Thursday read, “Once upon a time there was Milan.”
Milan’s next game is against mid-table Chievo Verona on Sunday.
“The defeat will not have repercussions on the league,” Milan coach Leonardo said. “There are 11 games remaining and we’ve got to stay focused on those.”
However, Milan has injury worries after key defender Alessandro Nesta was ruled out from playing the United game shortly before kickoff due to a right knee problem that could be another serious blow to Nesta’s injury-riddled career.
Nesta’s replacement, Daniele Bonera, injured his calf and was removed at halftime, prompting Leonardo to move Massimo Ambrosini back from midfield to defense. Striker Alexandre Pato also did not play in Manchester but is nearly ready to return from a hamstring injury.
Inter visits Catania on Friday ahead of its return-leg Champions League game with Chelsea on Tuesday.
Inter forward Mario Balotelli will miss the game after bruising his right knee in training Thursday.
With Walter Samuel suspended, Marco Materazzi could return in Inter’s defense alongside Lucio, with Ivan Cordoba an option at left back. Midfielder Esteban Cambiasso is also set to return after a two-game ban.
Catania is coached by Sinisa Mihajlovic, the former Inter player and assistant coach.
Mihajlovic said he has been bombarded by so many text messages from his former teammates and players this week that he has turned his phone off.
“I’ll turn it back on after the game,” Mihajlovic said.
Third-place AS Roma, which trails Inter by seven points, visits struggling Livorno, while fourth-place Palermo is at Udinese.
Juventus, which trails Palermo by two points in the hunt for the last Champions League spot, faced Fulham in the Europa League on Thursday before hosting last-place Siena on Sunday.
Juve edged Fiorentina 2-1 last weekend and the Tuscan club was ousted from the Champions League on Tuesday by Bayern Munich on away goals.
Fiorentina is still fuming over a first-leg goal from Miroslav Klose that appeared to be offside. Tied for 10th with Bari and Chievo, Fiorentina’s chances of making it back into the Champions League next season are slim.
The Viola visit Napoli on Saturday.
Also this weekend, it’s: Bologna vs. Sampdoria; Genoa vs. Cagliari; Lazio vs. Bari; and Parma vs. Atalanta.
