I am trying to get in to European football but one thing troubles me. I understand the basics of European football but cannot seem to find any information on how bad football clubs get good. For example, in American football, almost all the NFL teams have been good at one point and the majority of them have achieved the highest honor in American football; a Super Bowl victory. Another example, the Chicago Bears are very bad this year but have had a tremendous past with lots of glory and winning seasons. Also, it is almost a guarantee that within the next 5 years, the Bears will be back to their winning ways. This is attributed through trades, free agent signings and good draft picks. Now, this differs from the English Premier League because only a select few clubs have achieved winning the Premier League. So, how does a team like Burnley, Sunderland, Hull City or any other unsuccessful clubs ever achieve any real success or are they just doomed for failure. They obviously dont have the finicial strength as the big clubs and there is no draft system like in the NFL so how do they ever bring on enough good players to win it all?
