There were a few teams where a team cohesion and system elevated them very significantly — even though every successful team would have individually brilliant players.
So I won't use the likes of Pep's Barcelona or Netherlands-74, but a couple of examples of teams where the system had a clear prevalence over player's individual skills:
1. Ajax-1995. It had some brilliant individuals (I'm a big fan of Litmanen, they've had young Davids & Seedorf and old Rijkaard there), but when you compare Litmanen to all-time great number 10s like Maradona/Zico/Platini/Zidane you'll see a clear gap in talent. He was flanked with Finidi George and Marc Overmars — again, hardly all-time great attackers, and up front they've had an interchangeable pair of Ronald de Boer (not even a striker originally) & 18 years old Kluivert. When you look at this set up, you won't expect an all-time great team, but that side played absolutely magnificent football:
Overmars - R. de Boer - George
Litmanen
Davids (22 y.o.) - Seedorf (19 y.o.)
Rijkaard (33 y.o.)
F. de Boer - Blind - Reiziger
van der Sar
In a few years — between 1998 and 2000, when all of those young footballers would reach their peak, Netherlands would have a squad stacked with world-class players, but at the moment those were mostly unknown youngsters.
2. Any Lobanovsky's team. He usually had one world-class player per generation and a bunch of good/very good ones, but his teams played brilliant football and often outplayed teams filled with much more talented individuals. He really had only 2 all-time greats playing for him throughout 3 very successful decades (Oleg Blokhin & Sheva), but Igor Belanov is a good case for Lobanovsky's influence — he had won Ballon d'Or in 1986 and he is probably the least talented player to ever receive the award (and I actually like him). 1986 Cup Winner's Cup final; 1988 Euros semi-final (USSR vs Italy)... the level of performance is mind-blowing. It's a perfect example of a well-built machine that elevates even average (on an all-time scale) players to insane heights.
So yeah, those are the most extreme cases. And then there are tons of examples of systems that had elevated world-class players to an even higher level — compare Pep's Barcelona to everything that came after him (although when they've had the Neymar-Suarez-Messi trio their individual quality and chemistry was so good that no system was needed).
Ole certainly has a system and those who say that he doesn't are, well, simply wrong. But he's not a very shrewd tactician that would be able to build a system that balances out our entire play (defensive & offensive one) and negates the obvious weak points that we have as a collective, and it's hard to imagine him suddenly learning that ability on the way.
