We can agree to disagree on the last bit, I think anyone with half a brain would know that if a team struggling for goals signed the striker with the 2nd best record in France (at that time) it would increase their goal tally and give an additional three points.
Yes people can say that if he got injured he may not have played so well etc, but barring an injury in the first game he would have given a massive lift, instead, he gave a massive shock and sent us down. Of course we can't prove it but it's obvious.
Agree with the rest, he made some mistakes but without his promotion, we wouldn't have had the money to make the mistakes. If we had employed any of the others instead of him, we wouldn't have had the promotion in the first place.
