I think you are correct it has been difficult for any centre forward to do well few crosses and opportunities Christian Benteke did well in the second half of last season but I don't see him being the answer.
Jean-Philippe Mateta has been given more game time than most preseason he has looked a real threat hit post and bar against Ipswich three other chances, scores against Reading. Mateta is a goal scorer as he showed in Germany and will be for Palace.

Yeah, fair enough. I don't think the short, sharp passing suits him much. But he can spray a ball and split defences etc. You're right, the new style might not be for him. Would be a shame imo. Love Luka.

I would forget Clyne and go for Jonjoe Kenny from Everton, they may even take a swop deal for Luka.

Rumours (I know) indicate that our new manager will send loan striker Mateta back to Germany. Think that will be a sensible choice. In spite of his Brighton goal - reminds me of a certain striker we loaned from Arsenal a couple of seasons back. Sanogo remember? That was praised by Alan Pardew as a player "with tremendous promise!"
