this is the fact that some team are spending more than the other team

FACT is not excuse

I agree with you that not having enough money is not the most valid excuse to not win the league but it is definitely a reason. I am sure you would agree with me on this. Yes, there are other ways to be successful, but with enough money, its just so much easier. I have never claimed that we don't have enough money to win the league. What I always say is we don't have enough money to compete on a level playing ground. It is definitely winnable, but it is going to be harder compared to our rivals.

And to compare the 90s team of MU to the current Liverpool crop is unfair. Although Ferguson did not outspend his rivals by a mile, he was definitely among the biggest spenders. Plus you had a lot of good players coming through the system at the same time, which is really rare and this process takes a while to achieve.

Ferguson had 8-10 years to tweak his youth policy to bring about that golden generation and its only fair that Rafa is given the same amount of time if you are going to judge him based on the players that come through the ranks. And yes, GH does not count, our youth policy until then was not the best to say the least. I'll admit that.

As for Arsenal, like I mentioned earlier, not having enough to spend is one of the factors. They managed to find a way to work around it. Kudos to them. Still does not take away the fact that financial muscle has huge implications on a team's title aspirations and performance.

Your core was vital to success.  But you needed the millions to surround your core with Rooney, Rio, Christiano and others.  So its a milk + nice tea power = to nice teh tarik thingy...
I am of the opinion that SAF IS the most vital ingredient to MU's success. But after that, i cant differentiate if its the core youth players OR the millions that contributed.
