Haf... criticism of Kone is not criticism of you (unless you of course have some personal link to him - which I'm sure you would have told us about).
I would have had him here for the price Wigan paid at that time - it was a 'why didn't we get him?' having seen him bang a few in and tear us apart. I was happy/dubious when we signed him - it seemed steep for his age/pedigree. Many could/can see his qualities but he wasn't an exciting signing. He has been so unlucky as he missed a few sitters vs Stevenage and West Brom (I think?) and then obviously got that injury. He's then come back into a under performing team after a very lengthy injury. Overall his signing has been a very poor bit of business - there's not a stat in the world that can prove that otherwise. Should fans be optimistic that he'll come good? I personally don't hold much hope.
Lukaku on the other hand has scored goals, he's young, yes he's very raw but he is what we've been missing for many years - the big 'number 9'. Us fans need this hero to worship and yes he deserves his share of criticism - every player does this season! We paid well over the odds for him but we could get that back this summer should we need to sell - I hope we don't as he will get better and better especially if we can rediscover the form of last season.
There's nothing personal here just the fact that we all want the best for our club - Lukaku's filled us with optimism and earned praise/defense, Kone has given us very little (through no fault of his own).
