It's supposed to be an initial bid. The actual targeted fee should be around € 18 - € 20 million.
Mascherano: € 22 million Market's moved on since he left, and he was 26 and has the highest fee out of all of the following players anyways.
Khedira: € 14 million 1 year left on contract when sold
Özil: € 18 million Rejected contract extension with just 1 year left on contract. His dad said pretty much that he would go to Real anyways. Not bad price for either club for a youngster with 1 year left, despite his quality
Reus: € 17 million Buyout fee was 18 million euros. Bought for 17.5m. Clubs fault for such a low buyout fee.
Sahin: € 10 million Criminally underpriced, as he had a 10 million buyout fee for non-German clubs.
Kagawa: € 16 million 13-17 million quid, and he wanted us and they'd lose him on a free if they didn't sell
Cazorla: around € 20 million Malaga are financially fecked, they're selling everyone and can't get as high as they could've because their owners are withdrawing out of the 'project.'
Please explain why Song doesn't belong in the same price bracket as these midfielders.
2/7 players had their buyout clauses reached (well, to within 500k euros anyways) so I don't see how having a buyout clause lower than your 'market' value means that they ought to be valued that little. Several clubs would've (and probably did) meet their buyout clauses and I'm sure they would've been sold for more had they not had a buyout clause / one of say 100 million.
3 out of the remaining 5 had just 1 year left on their contract and had refused contract extensions, and thus would have a far reduced market value relating to Song, who has 2 years left.
1 out of the remaining 2 have a club which needed to sell him this window because they are financially fecked; even a relegated club wouldn't sell with this much impunity (Malaga)!
Only Mascherano you can relate to Song; and the market's moved on since then (as well as club revenues, TV deals etc). Anyways, 22 million euros isn't far from what people are valuing Song at; which is around 30-33 million euros.
I don't see how RvP can be had for 18-25 million quid, (depending on where he's going) and Song for just 12-15 million quid.
Arsenal are a club that don't 'need' to sell Song this year, they can offer CL football, they've been his club since 17 (on loan, and 18 permanently), giving him good wages at the moment probably, and are still a big club. Conversely, selling him this year would mean they can get a higher fee, and please the player if he wants to go; but to my knowledge he hasn't refused any contract extension at present; all those players you listed didn't want to extend their contract with their club at the time, and most had just 1 year left or had their buyout clauses met.
Song doesn't have a buyout clause (or a low one, anyways), and Arsenal can still convince him, and have at least the next 6 months to convince him to do so whilst still getting a big fee from him.
15 million is criminally undervaluing him for todays market; even 15 million quid is rather on the low side. I think him and Sahin for anything under 20 million quid is an invitation for us to pick up 2 very good players. I know I'd rather get Song (or Sahin) than RvP for 20 million quid. Heck, get both Song and RvP with the '40 million net spend' we're allowed, and sell Berbatov who wouldn't get a look in at all next season.
