It's not an easy job to convince someone else that you won't pay anymore when they know you have the financial means to. How do you make people think that, no, seriously THIS is the most you'll pay? The only way to do it is to take your time, look ponderous, like you are really questioning whether to go that high etc. that's what takes the time in my opinion. It was reported that Wolfsburg aren't giving us a definitive asking price to try and work against, which makes it even harder.
<50m would be a good deal in my eyes, if we get him for less than sterlings 44 then I think Everyone should be happy.
You have to sacrifice some players to do that - by being prepared to walk away - and the moment we do that, the fans will be up in arms saying 'why didn't we just pay the extra, we can afford it'. The only way we can enhance our reputation for being stalwart in deals is by being prepared to walk. But are we (club and fans) really prepared to do that?
Also, it's a total myth that we have unlimited funds, and I think some other clubs possibly over estimate how much we have to play with. Wolfsburg can easily think 50m is no great problem for us (which it isn't in isolation), but as part of a whole summer packager involving other high value targets, it CAN be an issue, and of course, they want us to sacrifice other deals in order to spend more on their own transfer).
This is where Txiki's on a hiding to nothing:
1) Some players won't want to come - nothing we can do.
2) Some players will be reluctant and need to be persuaded (usually money) - but that's not a good sign for an expensive buy, and it usually means they are costing more than they should, which has knock on effects on other deals.
3) Half the fans are wanting a big name players
4) The other half are demanding we're not taken advantage of and need to tell other clubs to sod off if they're taking us for a ride.
5) Precisely the same is happening with outgoing players, where half the fans want rid at any cost, and the other half want to hold out for what WE think the true value is.
Whatever he (or City) does, someone's not going to like it.
