I find it funny that he's going on about not being able to understand the horrors of being in war, and that he can't actually realise that he's telling us point blank that he can't possibly understand exactly what it means to be a manager, because he isn't one, therefore can't possibly know what it's like.
"you need compassion".... as a manager I think I disproved that, most managers during periods of success are not compassionate at all but will happily cut anyone from the team in order for the team to be successful. It's exactly when managers stop doing this that teams slip with Wenger/Fergie being amply proof of this. When they stopped cutting players that weren't making the grade and started giving contracts to players they'd known for a long time and clearly didn't want to just let free... is when their teams started to weaken drastically along with their competitiveness.
Fergie(who won more than Moyes ever will) didn't take training himself most of the time and afaik for most of his career. Fergie played football in a time that players got drunk, weren't athletes by any real meaning of the word, trained a little, got drunk after a game, played on dodgy pitches with significantly different equipment(heavier balls, much heavier boots). Do you really think Fergie had a complete 100% knowledge of what it was like to walk out and play himself in a champions league final, at the pace and intensity with which the modern game is played.... no, he wouldn't. Did he ever play against a player like Ronaldo, with his pace and strength on such a smooth pitch, with such a light ball, with the same level of fitness and running the same distances over 90 minutes? I think Fergie has an idea what it would be like, but little direct experience of the current game. Did he ever have modern surgery, sit in a hyperbaric chamber, eat or train the same as they do today?
Your assumption that you can judge player ability better than others because you're in the sport(maybe) is wrong, it's based on a stupid argument of "lots of people say it therefore it must be true".
Again I'll point out, you say Fellaini will be a great DM, Moyes, LVG, the Belgian coach and Fellaini himself disagree with you(and literally everyone else on the forum) and when he's played there I've watched him play awfully in that position... but your opinion is more right than mine because you're in football, but your opinion is more right than LVG's, Moyes's and Fellaini's.... this argument is logically false, clearly.
You are wrong about Fellaini, everyone knows it, yet we have that opinion and we don't play, and you do(supposedly) play, thus your random idea that being inside the sport means you know better, is also logically false.
