You guys overrate European leagues way too much, there's way too much cannon fodder among the top leagues, just watching the Champions League every season shows us this, too many one sided games which you can bet your house on. Do you guys think South American players come from these "easier" to score in leagues and magically get better when they cross the Atlantic and join European teams to rip apart these supposedly "good" defences were meant to have?
The likes of Oscar and Tevez(you should have seen the arguments for this one
) were meant to struggle and be bullied when they moved over to Europe if you believed some people, now their's tearing that none sense to shreds.
Don't get me started on the people who think Neymar will struggle in the "score as many goals as you want" Spanish League. Now, if the argument was that players struggle due to having difficulty in adapting to the culture and different way of life, then I would agree with you, not this stupid "They struggle cause European defences are better" bullcrap.
Your belief is not required
