While I appreciate the point you make about the price compared to the players you mention, you also have to consider that unfortunately we couldn't hope to attract the players above and we certainly couldn't afford to pay their wages within our wage structure.
We were actually on the verge of signing Benteke in 2013 for less than we eventually agreed to pay for Soldado before our manager at the time pulled the plug on the deal.
What makes you say that?
Since then Villa's hand has been strengthened by Benteke signing a new contract, but weakened again by his subsequent injury and his lack of goalscoring since he came back from that. I would harzard a guess that he could be prised away from Villa for about £20 million and that isn't a bad price to pay for him really. I guess the question is whether Pochettino wants us to play with a powerful, physical number 9 or ideally wants a more mobile, pacy one?
Villa seem to have been asking for over £30M all along - I'm not sure why they'd drop their price now. Villa certainly can't attract anyone to replace him and despite his current lack of goals desperately need to keep him.
