Clattenburg interviewed by FA

The Football Association has carried out a series of interviews with match officials as investigations continue into allegations from Chelsea that referee Mark Clattenburg used "inappropriate language" towards their midfielder John Obi Mikel.

The interviewees are understood to have included Clattenburg plus assistant referees Michael McDonough and Simon Long and fourth official Michael Jones.

The interview process was expected to be completed on Thursday night or Friday, enabling a decision on whether any action should be taken by the FA to be made early next week.
