No we haven't. But my thinking is that as it took all/most of our players quite a while to fully comprehend and put into practice the way Rafa wants to defend, its quite likely that any new players, particularly defenders, will take a while to adjust to this way of defending. If one had some experience of playing something near Rafas system with a previous club, I would have thought he would be likely to 'acclimatise' quicker than someone who has not. Thats all. Obviously, usually most players are brought back to defend set pieces against us, so its not neccessarily just denfensive players that have to adjust to this system. Sorry if thats come across a bit waffley!
