Yep most of the media is UK based which means generally players in the premier league will get more news and higher buzz so more dividends. Signing for Bayern has killed his future media buzz potential so killed his value. To make matters worse, he is a midfielder which is the most congested position so has neglible chance of being profitable in the performance buzz (I think a lot of people are missing this and the value of midfielders generally will drop once the season starts). Despite the crash, James is still heavily over-valued.
You need to decide what you are aiming for. If its performance buzz then defenders are the best targets. Alternatively, you could go for low valued strikers that you think will be linked with Premier League teams in the future - this is more of a gamble but generally everyone is linked sooner or later.
Alternatively, you can target proven buzz players who are likely to be in the media anyway - check Footy Index Scout which has a record of who has won the buzz previously in-season but try and avoid players who could leave the Premier League. Someone like Hazard is a gamble because if he did leave for Madrid his value would crash. Be wary of people saying "Player X will kill the performance buzz because he scores 30 goals" yeah he might score 30 goals but there are 70 other strikers to compete with most of which are goalscorers.
