34m/40m is not 'market price'. Heck, neither is 27m. We are the only ones who want this kid, there is no one else willing to offer that money for him, and for good reason.
He is a talented LB, but not as much to justify these ridiculous figures. We will probably sign him for around the initial amount we bid around 30m mark, but I can't see us going higher than that.
Also, unless anyone here can see the future, then we have no clue whether he will be a good buy or not. This claim that he will be here as first choice LB for the next decade or so is complete baseless assumption. Players can get injuries, or their development can stall or they can even regress, there is no sure way of knowing it. If he was such a sure bet to be one of the best LBs in the world, then a lot more clubs would be in for him.
It is a gamble for sure, every talented youngster is. So, becaue of the kind of money being touted, it is no surprise that we are cautious of the amount we are willing to splash here.
