Clearly the Joey Barton situation is a bit of a touchy subject at Rangers.

The veteran player is currently serving a ban from training following a dressing-room fall-out with a teammate.

The initial ban was extended by one week on Sunday for the former Newcastle, Manchester City and QPR midfielder.

Barton has also been charged by the Scottish Football Association with betting on over 40 matches.

In Wednesday's Rangers press conference, members of the media asked manager Mark Warburton about Barton.

But he politely refused to comment until the club's PR adviser stepped in to try and call a halt to the line of questioning. The press conference resumed 20 minutes later.
