Chance is probably something like "an opportunity to shoot on goal" rather than a shot on goal which may be what you have in mind.
I'll just have one more go at this.
The argument boils down to a pretty simple one.
I think that steady is she goes is the answer. I think we are creating enough chances to win games and that if we persevere then we will start to do that. I think radical change would be a mistake.
The other side of that coin (as put forth by Steve-O and a few others) is that because we are so woeful in front of goal (which we have been) then we must seek to create more chances because our conversion rate is not likely to improve much. I don't agree with this because I think the risks inherent in the changes Steve-O would see made are great, and the benefits he sees as a result are unlikely and far-fetched.
That's all it is folks. Two different opinions.
In my opinion, and I think there is evidence to support it, a two man central midfield is far too easy to play through for the A League. Indeed around the world the two man central midfield pairing is becoming a rarity.
If you look at the personnel we have available there is not a balanced two man pairing either. You could play Brown and McKain, who would offer you a lot defensively, but not so much going forward. You could play one of those two and any of Daniel, Leo, Caceres, or Diego, but none of that attacking four have much in the way of defensive ability, so you'd be asking too much of Browny or McKain. You could play Vinnie or Ferrante, but Vinnie is a poor man's Brown/McKain really and (although I hate to say it) Micky Ferrante can't really be said to be up to the level. He's had his chances.
Now if we had very athletic up-and-back-style wing players then we could perhaps play a four man midfield and expect those wingers to get very narrow quickly and defend. But again you look at the available players and the only one who might do that with any regularity is Ifill. The others (Costa, Leo, Daniel, Our Troy etc etc) are all very much "front of the pitch" players. Their strengths lie in attacking areas. They'll close a man down, sure, but they're not going to be very effective going up and back all day and wading in with the odd Brown-style bobsled. It's just not in their skill set.
So taking those two things as "fact" then, how do you pick your team? Well, you say: I know Browny/McKain can't do the job alone, so I'll put someone else in there to help them (Vinnie the other one of the pair). Then, I can't rely on them to be creative, so I need a creative outlet in the middle. Bingo, I need a three man midfield.
And the rest falls into place from there.
The other advantage of playing 4-3-3 is that it takes advantage of the attacking threat we can sometimes get out of Lochhead and Musky Mancat a lot better than a 4-3-3. Sometimes Locky can deliver a cross, which is a nice addition to the go forward arsenal.
I do have some sympathy for what you're saying though. I'm not convinced about Greenacre's ability to lead the line alone either. I wonder about playing Ifill like United played Rooney when they had Tevez and Ronaldo in the side. Nobody really leading the line (although nominally it was Rooney he was always peeling off into pockets to get the ball like a second striker). Greenacre would end up on the bench then though, and I'm not sure we're ready for that either.
I also see your point about getting people into the box who can finish (Greenacre and Ifiil in your scenario) and I would agree more but for the rest of it.
I think if you played 4-4-2 as you've described then one of Greenacre or Ifill would have to track deep so often that you'd end up genuinely playing one up front.
Lastly, Steve-O, I think you'll find that the reason everyone thinks you're a bit of a twat is the way you set your stall out. It is very confrontational. The tone of your posts (and sometimes the actual post itself) suggests we are all numpties for not seeing things through your eyes, which we aren't.
Your view has some undeniable truth to it. We must score more to win. We must find a way not to get pushed back into our own half. We must put teams away earlier in the game. But, try harder not to be a cock.
Incredible stamina. No shame. Yellow Fever.
