Jović is a fantastic striker but anyone that knows enough about Barcelona knows full well he doesn't fit into how the team play traditionally. It's a given and back when they were interested in him the sports pages comments were full of negative posts regarding the interest without anyone ever saying he was crap.
Real Madrid play a completely different brand of football and infact Real Madrid have never had a brand or style.

Back to the argument... Real Madrid can do these things and succeed, Barcelona can't which is why signing players that eventually don't fit in hurts Barça a lot more than it could ever do at Real Madrid because at Barcelona (as many coaches have found out), moving away from how the academy works eventually puts the the club in a football crisis as Terry Venables found out after his successful initial period. It took Barça over a decade to recover and it wasn't the first time it occurred either.
