Arsenal are trailing AC Milan by four goals and need an absolute miracle to progress to the quarterfinals of the UEFA Champions League. They aren't sending out a youth team because, well ... they don't have much youth to send out. Most of Arsenal's good young players and reserves are injured. They're playing some kind of 4-4-2/4-2-3-1 with three true wingers because they only have two fit midfielders. One of Theo Walcott or Gervinho will probably play as a striker. AC Milan have selected a first choice team for the most part, and have elected to sit some borderline players.
Arsenal Lineup (4-4-2): Szczesny; Gibbs, Vermaelen, Koscielny, Sagna; Gervinho, Song, Rosicky, Oxlade-Chamberlain; Walcott, van Persie
AC Milan Lineup (4-3-1-2): Abbiati; Mesbah, Thiago Silva, Mexes, Abate; Emmanuelson, van Bommel, Nocerino; Robinho; El Shaarawy, Ibrahimovic
Kickoff is at 2:45 p.m. ET, 7:45 p.m. local time from Emirates Stadium in London, England. You can catch the game on FOX Soccer Channel in the USA, Sportsnet World in Canada and Sky Sports in the UK.
