It'd be a bit of a cop-out to say, 'ah because he is the focal point', when he often pulls out wide and anyway, you could just as easily say the same thing for the others players mentioned, only with better players surrounding them!
Suarez has only had two full seasons in the league (he was brilliant for Liverpool the few games he played in the other season). Bit harsh to say he has only had one good one, 50% success rate. Just like, your favourite, Aguero.
Come on Zim, you've mentioned what it was like when we got Bergkamp in 1995, it wasn't like we were riding high with talent then, nor with who else came in alongside Bergkamp. We're a far better side now than we were then, we're in a far better financial shape now compared to then and look what followed. When it all started for Citeh with Mansour, they only made one signficant purchase, as they didn't have time to do anything more than that - Robinho! Look what followed there.
If we assume that we will settle with Liverpool for the £47 million Caught Offside say (and that of course is a huge leap of faith given they're a pub team website) then I would suggest we still have a more than decent amount left, especially with all the squad departures we have had this sumemer. That's kinda why I want us to hurry this along but I don't want us to miss this opportunity, even if we're buying a complete nutter.
