FIFA are set to investigate Premier League champions Chelsea over their conduct in youth transfer dealings, according to Daily Mail.

The Mail says that FIFA have confirmed that they are investigating the Blues over their acquisition of foreign players under the age of 18.

The west London club have previously been investigated by FIFA twice for similar charges in the last eight years. They faced transfer sanctions in 2009 due to their signing of Gael Kakuta from Lens.

Chelsea were also investigated for the transfer of striker Bertrand Traore last year.
