I agree with humagaia, to early to tell but there were similarities with his form at liverpool this season yesterday.
At times he looked frustrated and when substituted the look on his face was one of a person who maybe was doubting his decision a little?
He had no service yestarday and couldn't do alot more than he did, I am a reds fan so glad that was the case, but there is no doubting that once fully fit and with a few games under his belt, being one of the top 5 strikers in the world he will score goals for whoever let alone chelsea, one of the most talented squads about.
Liverpool not being in the champions league allows Torres to play in that competition for the blues so another reason the £50 million was paid, and of course he will add greatly to cause for their persuit of the European Cup.
Overall I think in time the money will be well spent, he is top top quality, and Chelsea have the luxury of having cover if he does pick up an injury that they wouldn't have to rush him back as Liverpool did because they relied so heavily on him.
And added to that I think his arrival will also give Drogba a renewed enthusiasm as he has had it far to easy over past few seasons...
