20 years ago you would have been right, but the game has moved on and attacking teams tend to dominate the big leagues and European competitions. You need a balance, but full backs need to provide an outlet and be good going forward almost as important as being good on the other side of the ball, maybe even more important than being good defensively.
I disagree, more often than not, the Champions League has been won by a solid defensive unit.
