I don't necessarily disagree with the overall point that it isn't realistic to assume we're going to do top business in just a few weeks. However, I do feel that one has to a lot of things into consideration.
You say that the likes of Liverpool, United and City are "splashing the cash", but that's because they can afford to. For a start they haven't been investing huge amounts in a new stadium. Then there's the simple fact of the window not only being short but also the World Cup but also it being harder to sign top talent, especially if players were at the tournament. The clubs you mentioned, in order to get new players in, are paying out on ridiculously over inflated deals. Look how much Liverpool just wedged out for a keeper FFS! About £70m I think it is! For this reason alone I think the forthcoming winter window will be busier than usual for a lot of clubs who can't afford to splash silly money.
I would like to see some key signings, but people need to remember who Levy is. He is not going to change overnight. As it is he has take, what for him, is a bold step this window in breaking the wage structure (and likely not just for Kane but players like Eriksen as well and the manager). While huge amounts of money are being spent on the stadium, that in of itself is unusual. So is it any wonder he otherwise is defaulting to his usual tactic of out before in and the cheapest deal possible? This is still Levy after all. If he hasn't changed in 17 years he's not likely to start now. So with that AND the difficulties of this window mentioned above, it really baffles me that just because Poch made a statement about being brave it means a big money signing or two will walk in two weeks after the end of the season. I'm sure Poch isn't stupid and knows the difficulties this window presents. And do you know what? It's all very well for Poch to talk of being brave, but he's signed a new contract since then, he knows the stadium is a huge undertaking and he knows part of his remit is to develop potential talent rather than buying ready made stars for over the top prices.
So I personally I don't see the latest ITK as Levy's failure. I see it, frankly, as the most likely way this window was going to play out and had we heard anything else I would have been surprised.
Hope that kills. Watch them dangle some more hope with a contract announcement tomorrow.. Bastards #spursy
