Political, Religious or Personal Statements

In addition to receiving a caution during the match for his goal celebration after he scored in the EPL match between Wolves and Sunderland on Sunday 4 December 2011, Sunderland's Kieran Richardson should be sanctioned post-match for his undershirt statement.

Players who intentionally flout the rules should be sanctioned by their clubs as well as by the competition organiser

The LOTG state:

Players must not reveal undergarments showing slogans or advertising. The basic compulsory equipment must not have any political, religious or personal statements.
A player removing his jersey or shirt to reveal slogans or advertising will be sanctioned by the competition organiser. The team of a player whose basic compulsory equipment has political, religious or personal slogans or statements will be sanctioned by the competition organiser or by FIFA.

Can we expect the FA and EPL to take action against Richardson, and also against Sunderland? Or will FIFA step in?

Furthermore, since players are employees, perhaps their clubs (i.e. their employers) should take responsibility for the behaviour of their players and fine them. This makes sense since players (employees) are, and are seen to be, representing their club (employer). Clubs would not be wrong to impose a fine on their employees. This will make their players think twice before deciding to break the rules and promoting their own self-interests before that of their clubs.
