There's no doubt football has changed a whole lot when compared to several years ago in both good and bad way. Managers significance during the game has increased with tactical preparation being the key to winning matches and not all choose to go about it in a fair way.
We've seen a lot of talented players just vanish and disappear from the face of the earth within a couple of seasons, particularly in the English Premier League, due to the rough reputation it has earned, where fouls can be often overlooked in favor of defenders and some teams have found loopholes in the football rules to gain advantage. Stoke City comes to mind with them being one of the dirtiest team since their promotion. Even though team is arguably short of naturally talented players and has been since their fairly recent promotion to the EPL, they've managed to survive for 3 seasons now, courtesy of their defensive-minded approach to almost every match.
Liverpool's Luis Suarez has been causing a lot of controversy since his move from Ajax in January 2011, mostly attributed to his diving, but lately, Gareth Bale has been under fire from the media for his behavior, but Bale is one of the most fouled players in Premier League and probably often needs protection from the referees. He recently called out Charlie Adam for a rough tackle in friendly game between Tottenham and Liverpool during summer, this being Adam's second brutal challenge on Bale within a year.
Theatrics can often bring disgust to fans faces, but there's little doubt game could benefit from better player protection.
