Milan had the game wrapped up in the first 30 minutes. Kaka didn't even need 90 minutes to do his damage. They were winning by 2 goals with 2/3 of the game left, they allowed Bayern the possession because they had practically qualified for the semi's, they didn't need to score any more, or are you suggesting they should've gone for more goals?
How many clear cut chances did Bayern exactly have? Their possession meant feck all, because Milan had already done the damage and were more than comfortable holding on to the advantage. Kaka didn't need to make Hargreaves look average again, nor did Gattuso or Seedorf. 30 minutes was all that was needed for that to happen TWICE and knock Bayern out!! It's not that difficult to understand, really.
I would always suggest you go for more goals. Would you actually argue that you should ever sit on a lead unless it is totally insurmountable? The run of play was against Milan from the opening whistle. Are you actually suggesting that Milan had any choice in how the game unfolded? They defended because Bayern in no small part forced them to.
They may have been content to play in this manner, nick two goals against the run of play. It very well may have been their plan, it is the general approach to tough away games in Europe is it not? However to suggest that Milan was able to score at will is extremely disingenuous. Yes, Milan scored two goals quickly. Yes Milan scored two goals on what was basically their only two chances of the game. The evidence would seem to support that Milan could score at will. It would look like that if you were 11 years old and lacked any sort of analytical ability.
I don't know offhand what Milans shot to goal ratio is, but I would conservatively guess it is not 100%.
Milan scored two goals against the run of play. Was this a tactical ploy by Milan? That they chose to sit back and hope that Bayern had no bite to go with their bark because they were so heavily depleted? I have no idea and neither do you. All we can do is analyze what happened.
What happened is Bayern had more chances and more of the ball. They failed to score. Milan had 2 decent chances and they scored both. Was Hargreaves to blame? It is a team game. He is no more responsible than anyone else that played in a defensive role in that game.
People need to get over the whole notion that if anyone scores when Hargreaves is on the pitch he has failed in his job. You don't believe it and you are just setting it up as a straw man to easily knock down.
The fact is, Bayern put up a much better fight against Milan than we did. They did it with not only an inferior first team, but they did it with half of those players out and many of the rest playing out of position. Hargreaves was a big part of that. It's not that difficult to understand, really.
