Actually I think the reason Carlo swapped Janku for Paolo was width. Coz if you saw the match u woulda seen the way Palermo packed the centre of the field(in their half). It's conceivable Carletto thought this would be the only way he could get a goal in namely putting in a fullback.
Also keep in mind, Paolo came on and never really looked like playing an orthodox LB position. He was more of an advanced wingback, and he did make some great crosses, which on that night Janku was not able to do as well as we know he can. Don't forget Paolo did get that shot on goal.
We also can't neglect the fact that as coach for a large club like Milan, you cannot afford to go for broke, like say a smaller club can. If you're 1-0 down in a league match, besides equalizing, you also have the responsiblity of making sure the lead doesn't increase, coz things could make it worse.
The reason we lost came down to 2 silly defensive lapses. One of which was by the best defender in the team and the planet(?). Also don't forget you can say Carletto shoulda introduced more forwards...say who again?
Boriello? Oli came in within a gap of 10 minutes, coz at that point of time the style of play Milan was adopting(when Paolo was brought in) was to crowd the box...and you don't need too much of a footballing IQ to know that when u crowd the box 2 box strikers is what u need.
Now seeing that his midfield was on that day, just so pitifully ineffective(please keep in mind that Carlo must be just as hampered by the lack of ability shown by Seedorf, coz Seedorf is a very central part of that offense, Kaka alone is not good enough), he brought on Oli immediately removing that crowded box strategy.
So essentially he made a new game plan and then he changed it seeing it wasn't going too well, all in the space of 10-15 minutes.
Ergo, Carletto isn't slow, he isn't stupid. You don't win a scudetto and a CL by being that way.(the WC maybe

) He is immensely hampered by a lack of form in his star players and a lack of quality in his reserves. He is just too classy to crib about that in public and instead says the team will work hard with what they've got.
In other words, he's being positive and trying to be as harmonious as possible. What's stopping him from washing his hands off the matter and saying, 'Galliani screwed me!'. He knows nobody can raise a counter point, yet he doesn't do that.
If we did erase that point deficit and get through to the CL group stages it was coz of him and his rotation policy. If there is one thing you can blame on Carlo, it is that he is conservative(don't say too much so, if you think a little bit harder, you'll see why!), what would u rather have, a kamikaze??
Would you rather win big and lose a few or win small and not lose much at all. Don't forget Carlo doesn't have an option, he has to take option B, coz of the position Carlo finds himself in. With a weak bench, an aging team and a points deficit, you cannot have ur players exhaust themselves going all out to score big, unfortunately this season we might have to resign ourselves to grinding victories, coz sometimes the points are more important than aesthetics. I know it's a lousy kind of football, but I'll forgive Milan this one season, if we can get a good finish.
Carlo has my vote for this season and the next. Unless Milan get out-thought regularly and not out-played as we have been recently I cannot put full blame on Carlo. Also all those of you who are still not aware, this isn't like the EPL where managers decide their transfers. Carlo is given whoever by Galliani and Braida, and he has to make-do. At the bes t he can make a request. We know for a fact that his (one) request was thrown out the window. So carletto is doing the best he can, and I will back him up. Coz for once, I don't think I can do a better job

Arsene Wenger couldn't do a better job...why coz Arsene builds a team into a great one, here team building is not upto the coach. The coach trains, the coach makes tactics, the coach does not choose his players.
Lastly on the Gila issue, I reserve judgement on him. I refuse to accept that he is classless. But I have to admit there's a limit to how long a striker can go without scoring. Lack of form can be an excuse only for so long. He's not had too many years of brilliant scoring in him to be forgiven an entire lousy season. I know his situation is not entirely similar to Adriano simply coz Adriano is a bit of a whiner, but there are similarities. Inter has treated Adriano rather shabbily, but it's not all unwarranted. He's had exactly the same complaints as Gila. We can't let Gila's better personality and team spirit cloud our judgement for too long.
And I have to be honest...I'd rather have a less-than-Gila striker as a regular whom I know I can rely upon for 15-20 goals every season, than having to wait with bated breath for Gila to reach his 20+ potential.
So what do I have to say about Gila? His position is shaky, very shaky, but the ground has not fallen beneath his feet. I guess he's our Lampard for this season. I don't think I can give him more than a month to shape up and start scoring, else I hate to say we'll have to find a replacement. We just don't have the luxury of enough players in form to carry one star player who is out of sorts. Man U can do it with Rooney, Chelsea with Lampard, Inter with Adriano , we've got j@ckshit if Gila is out.
I'm sorry guys but this season we need the points just too godaaamn bad to put loyalty and hard work over effectiveness in fact over all else. I won't disapprove of the contract extension, there's not much else the management can do as a confidence booster, the ball I'm afraid is at Gila's feet, his play to make.
For what it's worth, Forza Gila
