Jonathan Sutherland introduces a busy weekend of action in the Scottish Premiership, which includes Dundee United's trip to face champions Celtic. United, who came off second best during the two sides' marathon four-game run of meetings at the end of last season, will be looking for improved fortunes under new manager Mixu Paatelainen.

New Motherwell boss Mark McGhee takes his side to Pittodrie to face his old club Aberdeen, and cup-holders Inverness CT take on 2014 winners St Johnstone. Elsewhere, Partick Thistle welcome Hamilton, Hearts entertain Ross County and Kilmarnock travel to Dundee.

Also, selected Championship action.
