You haven't understood any of a carefully worded post, and I frankly can't be bothered explaining it.
The Kuyt and Osman comparisons are very relevant for a valuation exercise if you actually put some thought to it. Here are some more names from the last 5-7 years that you should consider - Malouda, van der Vaart, Dempsey, Kalou, Michu, Benayoun, Nani, Sigurdsson. These are far better valuation comparisons than the completely laughable references to Iniesta and Goetze. These are goalscoring attacking mdfielders in the PL who his statistical production is comparable with. Why shouldn't value (after accounting for inflation) be referenced accordingly?
Even assuming that he's far more talented than any of them (and I'm not necessarily willing to concede that - VdV, Malouda, Michu are/were very talented), then you have other comparisons - like Eriksen, Coutinho, Kagawa, Belhanda, Marvin Martin, Kovacic, Pjanic, Firmino, Djuricic - and that's just off the top of my head, who've gone for a pittance compared to the 25 million figure being bandied about for Lallana.
Have you seen what most of these guys have been doing for the past 2 years - for club AND country? Some of these guys have over 20 senior caps, and are their sides' best players - it's quite different from breaking through into an English team largely devoid of talent, managed by one of the shittest managers in the world and making an impact as a sub.
He's a talented player alright and he's done very well this season. And just for the record, lest some idiot likes to remind me when we've signed him that I said he was shit, I actually wouldn't mind signing him. But you've got to be someone having zero world view of football or some blindly parochial oaf, if you think that he's one of the best talents in the world worth paying 25 million for.
As for who gives a shit about paying extra money, that's the most retarded logic of all time.
Who gives a shit about the hard-earned extra 30 million CL money, I suppose then? Who gives a shit about the extra 30 million per year our zillion-fucking-years-in-the-pipeline stadium will bring, I suppose as well?
