A Key Tool
Wanting Bale over Fabregas is FM talk. You buy for the positions you are weak in first. Fabregas would improve us as a team more than Bale would.
I think this is debateable. Personally I disagree. I agree with your general principle about covering weak positions first, but where there are truly world class players available in other positions you can sometimes have a bigger overall effect, as the sheer quality makes up for the weaknesses. This is to a large extent why RVP turned out to be such a good signing last year. He is an incredibly efficient striker, thus makes up for the lack of clear cut chances created from a better midfield.
In a similar away Ronaldo was so good on the wing, there was little work that was needed to be done in the middle to get the wins. Just get it to Ronaldo and he'll rip apart the opposition and where he is heavily marked other average players can shine with the extra space and time they have on the ball.
