As a Latics fan I'm obviously biased, but I'll try to type this without any bias, just common sense

.
N'zogbia is now 25 so his best 5+ years SHOULD be ahead of him, he has plenty of PL experience and even though he's French, he's now been here long enough to be classed as a 'home-grown' player for PL and UEFA rules.
Over the last couple of seasons he's proven himself to be one of the best match changers/winners in the PL playing from the wing, he scares just about every full back he comes up against and has as much skill as all but a very select few.
He's had his troubles in the past, but has shown great charcter, drive and a desire to be the best for quite some time now, the label of 'insomnia' should have gone by now and even if many still accuse him of being a disturbing influence, he's shown none of it in a Latics shirt for a long time, in reality he's been just the opposite for us.
So, how do you put a price on such a talented player?
As he's only got a year left on his contract, he'll obviously not go for his 'true' value, yet compare him to other wide players and consider the way the transfer market gets sillier and more overblown every time the transfer window opens and the only conclusion I can come to, is that DW is about right saying he's worth £20m, we all know we won't get anywhere near that for him, but if he goes for anything less than about £12-14m, we've been mugged and even at £14m, someone will get a real bargain.
