I'd be alright with Kone. We'd all like someone who's got 20 a season in him, but perhaps we don't have the money. The lid's got a great touch on him, holds the ball up superbly, has enough pace and is a good enough finisher to do a very solid job for us. With our standard of service, I'd fancy him to get 12 to 15 goals, which is already a big improvement on what we've got.
Also, if we could get Mirallas playing off the striker (please, Roberto) I think, based on his goal scoring in the back end of last season when he got fit, we've got a 15 goal a season player there, so we wouldn't really need a 20 goal a season man to push us towards the top four. All we need to push on is, well, pretty much exactly what Kone is. A big strong lad who has all the attributes to play the lone role, can add a few more goals and can contribute more to our good football, which I think he will. He's a really tidy player.
His age is a shame, but one good season from the lid could mean the transfer pays for itself and more.
