i am a win ugly over lose pretty approach to team sports. but sure the sweet spot and goal is to win pretty. for instance liverpool is no elegant team nor klopps dortmund before but i can only respect a group of men working so hard for each other and as a collective in a fair sporting way.
Well, you see, the first WC I watched live on TV was the 1966 one. I was 11-12 yrs old in a summer-camp like thing, kept for talented young footballers, we did nothing else but played whole day in four different pitches and when the WC games started, we watched them all collectively. B&W TV and dozens of small kids, ambitious ones, all of us wished to be pro footballers and the next Pele.
Our Hungarian team beat Brazil by 3:1 and the game was spectacular. The kids were in trance, shouting and crying and there was one single guy there - myself - who was relatively calm and emotionless, trying to enjoy the win but simultaneously watching it with an objective open eye. That one single guy (me again) was the only one who made it to be an internationally acclaimed professional who was also once invited to play for the selected-world-team.
There is a reason behind that (specially after re-thinking stuff after 50 years have passed). Pros need to enjoy playing, remain relatively calm, rarely love or hate other footballers, but before all: we have to KNOW when a triumph came with bad or lucky play, and when winning was truly and actually deserved.
The mere "winning mentality" on the pitch is not enough in itself, because there's a possibility that after an important game won, you start thinking that you were actually good and that ruins everything. We always had to play with an open mind, knowing if we played horrible or great, because that's the only way a footballer can develop further.
Just counting the triumphs can be very very misleading and baleful.
So I grew up like that, always remembering that the QUALITY matters above all.
The rest can be matter of luck, disposition, an idiotic referee, even weather and other circumstances, but the most important is to know when you and your team is playing well, regardless the actual result.
I had played bad in important games when I scored twice and played relatively well when others scored or the team actually lost...
BTW, Respekt_III is right, Liverpool can play very enjoyably.
