As Milan flew back from Seville in the early hours of Friday morning, Gennaro Gattuso was already drawing up a game plan for Juventus' visit to San Siro this weekend. "We've got a two-and-a-half hour flight," he said, "and we'll get to work immediately. We won't sleep." The injuries Milan have suffered of late are probably enough to keep him awake anyway. Gonzalo Higuain hobbled off, clutching his back, in Sunday's dramatic win in Udine. Then came the news that midfield organiser Lucas Biglia was travelling to Finland for surgery on a groin problem that will keep him out for four months. Mattia Caldara, the centre-back Milan exchanged for Leonardo Bonucci, won't be back until after the New Year either and watching Milan's 1-1 draw with Betis on Thursday night, one Italian phrase in particular came to mind: piove sul bagnato. "It rains on the wet." Mateo Musacchio was stretchered off with a neck brace on after a nasty collision with teammate Franck Kessie. "Mateo's fine. He's South American," Gattuso smiled. Hakan Calhanoglu found the pain too hard to play through following a stamp on his foot and also had to be replaced. The casualty list is longer than Gattuso's arm and with Giacomo Bonaventura's knee flaring up, you look at Milan's midfield and wonder if the manager might have to come out of retirement. Either that or he goes with the guys from the Dudelange game: Andrea "Mr. €30 million" Bertolacci, Jose Mauri and Tiemoue Bakayoko.Mario Mandzukic Juventus Jersey "We'll battle on," Gattuso promised. "Excuses get you nowhere." Meanwhile, Juventus aren't as battered and bruised from a physical point of view as Milan but this midweek did leave them stunned. Juventus lost for the first time this season and the circumstances of their defeat caused some consternation. Leading 1-0 at home to Manchester United in the 86th minute, the Old Lady was poised not only to qualify for the Round of 16 but to go through to the next stage as group winners. No one expected her to throw that opportunity away, particularly in light of how she outclassed United at Old Trafford and created enough chances to be out of sight on Tuesday night, too. Sami Khedira hit the post and Paulo Dybala struck the bar, while Miralem Pjanic and Juan Cuadrado both spurned glorious chances shortly after Cristiano Ronaldo's magnificent volley put Juventus in front. "We dominated," Ronaldo said. "We should have won the game easily, by three or four goals. Manchester did nothing. They didn't deserve to win." But if you give away cheap free kicks around your penalty area and invite situations that have repeatedly caused you problems this season -- like defending crosses, for instance -- then you're asking for trouble, and United took full advantage. It was only the third time a team has come back from behind to beat Juventus in the Champions League in Turin.
