No, of course he's not. But they effectively didn't pay anything for him. Last January, they swapped Torres (£50m) for Carroll (£35m) and Suarez (£18m). I would say none of those players are valued correctly in those deals, but it doesn't matter because Liverpool's outlay was something in the region of £3m and they swapped one underperforming striker for two more effective ones. They did EXCELLENT business.
Suarez cost £22.5million. Liverpool alternatively could have signed someone GOOD for £35m, which would have been even better business.
