All I'd add here is this gelling issue, I don't buy it, you can improve a player touch and technique, certain things are coachable, but a lot isn't, intuitive vision for a start, you can't teach what players like Eriksen and Modric see in a split second when a pass is on, otherwise everyone could do it. Dembele is a prime example here, great feet and technique but rarely see's a telling pass.
AVB has bought 7 players is it to supposedly improve the way he wants his team to play, in fact all signings since Sig have his mark on them, and although he didn't spot Sig himself, he ok'd the deal, presumably having cast his detailed eye over the player. To me a few look like a fish out of water with it to me, indicating poor use of the Bale money.
I think there are two players that currently look to be a poor use of the Bale money:
Soldado
Lamela
Unfortunately they amount to 56m!
This goes to show though that it is not easy buying players of this calibre.
I think Lamela will improve in time, as will the rest of the attack, but whether he will ever be a 30m I don't know.
We don't have that kind of time with Soldado though, as it is not a confidence issue its a service issue. We are letting him down and possibly costing him his world cup place.

We do like a bit of risk taking in our defenders at Spurs but he hasn't shown the defensive quality to me so far. Kaboul, for example, was quality last night yet still did that cheeky back heel and skinned the Hull player by the corner flag in our half at one stage. Chiriches just looks like he doesn't want to be a defender.
