Former FIFA president Sepp Blatter is facing another corruption investigation after the ethics committee of world football's governing body announced it was opening proceedings against him and key lieutenants Jerome Valcke and Markus Kattner.

The committee's investigatory chamber will investigate possible violations of FIFA's rulebook that relate to bribery, conflicts of interest and general conduct, while Kattner faces a further charge related to a breach of confidentiality.

The case is understood to be based on the huge salaries and bonuses the three men allegedly paid themselves at FIFA, and the alleged leaking of information about new FIFA president Gianni Infantino to the media.
