I reckon if Liverpool sold him, they'd have to buy someone of a similar skill level, of which their are few. Otherwise Liverpool lose out. And then just replacing him seems redundant, might as well keep him - he seems to be content now? Has Champions League to look forward to too.
I think if Bale is worth 90 million, then yeah, Suarez is worth more. I don't agree with the pricing, in saying that, but it is what it is.
