Well I won't talk about the match in general.

The players however will be discussed indirectly. I usually agree with almost all of what you say, Zed.D, but I can't get myself to agree with half of the rankings. Let's see here:
Abbiati: The reason we went a goal down. This thug seriously needs to get his act together or get ready to warm the bench. He makes good (even great) saves, and has been on form I give him that, but his habit of throwing the ball at the opposition team's feet is really creeping me out. He has been doing this consistently for a while now, and even today he stupidly gave or kicked the ball at a Sampdoria player.

Today he kicked the ball with eyes closed, it ended up outside, throw in, Nesta got under pressure while covering, gave away the corner, and they score. Sampdoria are the "King of Draws", the 1-1 was incoming all through the second half.
Nesta: Not his usual self, but a Nesta on his bad day is still worth half a dozen other defenders.
Abate: He did what he could, and did great. Probably not "Man of the match" but darn near close. I get what you guys say that his crossing is literally nil, but the guy has pace, and he made more than one good tackle while defending. Vital tackles, even. He is not Milan starting material, but then neither is Antonini, neither is half the squad for Pete's sake.

But if he keeps it up like this, and keeps on improving, I'll have him on the bench at least at all time. Remember he had both CRON and ETO in his pocket two consecutive matches.
Bonera: This sucker was another reason for the goal.

There is a thing called offside trap, Bon!
KPB: Probably the only major club this guy will get playing time in is Milan. Mediocre at best, another one in the Antonini/Abate/Bonera category. Brings lots of promise, under delivers. I have been saying this for time now, there is nothing special I have seen from him once. Lots of quantity (and heart), little quality (and results). I can't believe Flamini did not get the nod ahead of Flamini.

Having said that we do not have other options, so Kevin will do. For now. Just have him with Flam or on the bench otherwise.
Seedorf: This guy does not deserve talking about more than a sentence. R80 (for all his flaws) did more in the 3 minutes than this so-called genius in the whole 90.

Nice way to fool people into believing you are a vital and integral senior of the squad. Missed a good chance, okay, no worries. But when you have Ambro putting in more effort and killer passes than your team's #10 then there is a major cause for concern. For all it's worth, I just hope both him and R80 were no where near this team - we need someone else here as our creative center.
Ibra: Having fun, are we?

Did good with the assist, but had no business starting (or even playing) this match. Luckily or unluckily, Allegri never heard about the word "Rotation". So unless things change, Ibra's bad days are gonna be Milan's bad day, and his good ones are gonna results in 3 points, more often than not.
Allegri: The coach gets a 1 for showing up and yelling at players. Out of 10 that is.

Seriously, two players who should have started get in after the 90th minute mark? Allegri better learn his subs, or he's gonna get subbed himself sooner than he knows what hit him. It's okay that we are still first, how much is that because of the coach is up for debate, but most of time we should be subbing our worst player on the pitch on the 45th, throw in another tactical change at 60th (depending on the state of the match), and try and slot in an absolute youngster in the 80th, give them a chance to gel with the main squad for ten or so minutes every match. Every match. There are certain exceptions, injuries and all, but that IMO should be the base template of substitutions.
I can type more, but the rest of the team put in an okay effort, considering we are without Pato, Pirlo, Inzaghi, have Bonera at the flanks, a virtually dead (killed?) Ronaldinho, and Gattuso who's starting ahead of Flamini day in and day out.

And oh, a coach who Not happy with the result, but can't say we deserved any better.
Justice is served.

Enjoy the pies, guys!
