You could go out and buy a £40m striker, there is no guarantee he will stay injury free. Look at shearer, for both Blackburn and Newcastle he was hit with a big injury at the start of both club careers.
For some reason the doubters who were against kones signing right from the start seem to use an injury to validate the argument.
For me the £6m spent on him was RM realising he needs someone he knows will give him what he needs on a limited budget.
I hope the lad gets fit and makes a vital contribution for us.
