If managers don't matter and players do everything by themselves (sure, their fitness is also controlled by their own whims), then how could Porto and Inter win the CL at all? Especially Inter against Barca, which had far superior players?
Also, stop equaling boring football with ineffective or incompetent one. Yes, Chelsea plays boring, but their tactics are intentional. There is no other team that fares better without the ball than Mourinho teams, whatever they are. The latest match between CH and MU corroborated that fact once again. Catenaccio of 50s Inter was even more boring, but just as successful. Aesthetics don't enter into this at all.
Allow me to put you right:
a)
If managers don't matter and players do everything by themselves
That is not what I said at all. What I said was that the role of managers is exaggerated by most football fans/pundits. Let me also add that this is done, partly because it is convenient to "personalize" complicated issues, and partly because going into full analysis takes time and effort (something that many people do not have) and partly because fans of football clubs are loathe to admit that their players (15, or 20 or 25 men) are not good enough. It is much easier to take psychologically that one man is the problem, and not 25! There is a big difference from claiming that managers' role is exaggerated to saying that they play no role at all. I hope that much is clear.
b) Fitness has to do with an insane amount of factors again, hence why people so often avoid this most crucial issue. How many games/minutes a player has played, the stage of the season, consecutive tough games, age, nutrition, the way in which a team plays, nutrition, age, DOPING (!) genetics, training methods, injuries etc. What you need here is a professional managerial team, conscientious players that will not be partying/drinking/smoking/eating shit/boning girls too much etc etc etc... The way doping is managed (doping is an art and a science) throughout the season etc etc etc... Sure the manager has to be aware of at least some of these things, but obviously the people and agencies involved here are far greater than a single manager.
c) Like I have repeatedly said, since there are so many other factors (outside of managers) at play in relation to football results, and outside of the quality of players, you have to look for those. After the quality of the players, you have the fitness to which I have referred already (uber-uber-crucial in the CL) and of course blind-stupid-random luck. Just look at our game versus Celta a few months back, or our first semi against Chelsea in 2012 to see how luck can turn a game completely and utterly on its head.
For me, if we had beaten Celta 8-0 in that game, it would have been less strange than losing 0-1. But there you have it. In that Chelsea semi, had we won 0-4, it would again have been much more rational/expected/likely than the eventual 1-0 result. Football is a real bitch sometimes, and this is one of the reasons why it is so popular. The underdog almost always has some hope.
So how could Inter/Porto win the CL? Two main factors:
a) Fitness
When a team suffers less strain domestically, or when it avoids injuries, or when it has the opportunity to rest players before crucial games (while the opponent does not) or if that team peaked at the exact time of the big CL games. Or the management of doping. A team that wants to win the CL, has to arrange it so, that the beneficial effects of doping kick in at the right time (namely, the time of the CL games) Etc, etc, etc...
b) Luck-randomness:
Anyone who has been watching football for years and has a modicum of intelligence doesn't need any explanation on this one. The examples are infinite here.
