No, they are not very good footballers. I could name one of them who would certainly make it into Real's, Barca's, Bayern's, City's or Chelsea's first eleven. Maybe Rooney, but certainly not as the most forward striker. That needs to be compensated for. But yesterday I saw a team that did, a very well organised, trained and drilled team. You can call that shackled, I think is freeing their minds of too many things to think about during the game, because they have done in training what already could be done. During the game they can concentrate on their own game, and don't have to look who is where, because they already know.
Sounds like the good old English way, let's not gain any advantage by beeing better organized and drilled and leave the players with as much thinking to do on the pitch as possible. That worked well in all those EC's, WC's and European competitions the last decades. Utd could become 3rd of 4th every season that way, and get hammered in the CL in march by teams with better players or more advanced in team play. It sounds to me you're impatient for mediocrity.
