I haven't contradicted myself at all, I agree with you that spending is not the only factor,judging from their performances this season I also believe that Real,Barca and Bayern Munich are only thriving because they have papered their cracks with their business in the transfer window, they have quality players in every position - some obviously better than others but quality players nonetheless, the EPL teams as I have mentioned have spent poorly which has left them a level below Barca,Bayern and Real. Real Madrid have been crawling their way through the different stages of the CL, Bayern have produced questionable performances in some games and dominant ones in others they are definitely not the dominant force they were 2 seasons ago, Barcelona have been superb but with a front three of an in form Suarez, a vibrant Neymar and the greatest ever (my opinion) who wouldn't be? Barcelona's defence is still very fragile, they are good but far from dominant....what is my point ? Signing quality players in every position can go a long way in covering your flaws and making you look better than you actually are - A successful transfer window from Chelsea,United and Arsenal (one where they all spend on the areas they are currently lacking and I mean signing quality players ) could see those teams challenge those 3 giants next season - bold statement... I know, but I'm ready to stand by this statement if they complete the aforementioned task.
If this season is anything to go by, the so called dominant teams are only using one factor to win matches.
