The Bluebirds failed to defeat Reading in their last game of the campaign but managed to avoid dropping into the play-offs thanks to Fulham’s 3-1 defeat to Birmingham.

The Scottish international snapped a picture of himself taking a swig from a bottle of MD 20/20 and uploaded it to his Instagram story.
