I only saw the last 10 minutes of this Champion's League fixture, and I don't think I'll watch the replay this evening. Arsenal have had good success playing in Milan in the past; today, apparently, was pay-back time. The loss is not surprising, but the margin of the loss is quite disappointing. The Gunners have left themselves no chance to take the tie in the return fixture at The Emirates in two weeks. I suppose we shouldn't be surprised that the Gunners will fall in the Round of 16, especially given their lack of consistency throughout this season. They are still very much a team in turmoil, and things could get even worse in the coming summer if rumors coming out of Madrid about Robin van Persie turn out to be true.
Whether or not Arsenal qualify for the Champion's League next season, many changes are required to increase the strength of both the first team and the bench. The likes of Walcott and Arshavin just aren't good enough to be in the starting line-up (arguably, Arshavin doesn't even belong on the bench). Arteta is, at best, a pale imitation of Cesc Fabregas. They have quality in Oxlade-Chamberlain, Wilshire, Ramsey, Song, Koscielny, Vermaelen, and Szczesny, not to mention the MvP, RvP. But need much more strength in depth. To add that strength, Arsene Wenger will have to dig into the team's wallet, and if the money isn't there, Arsenal fans will need to adjust themselves to long-term mediocrity (as if it hasn't already been a long term since the Gunners won something).
