Joe Ledley scored twice as Celtic thrashed bottom side Dundee 5-0 at Parkhead to take another step closer towards retaining their Premier League title on Sunday.
Ledley opened the scoring in the 13th minute and James Forrest notched the second from the spot four minutes after the interval after Dundee substitute Matt Lockwood was shown a red card for denying Gary Hooper a clear goalscoring opportunity.
Dylan McGeouch, Ledley and Hooper added further goals to compound the misery for Dundee, whose new interim boss John Brown watched from the directors' box.
In the day's other game, Dundee United drew 2-2 with Hibernian after Johnny Russell netted a controversial late penalty.
Hibs looked set for all three points when James McPake cancelled out John Rankin's early opener and Leigh Griffiths struck in the second half.
But United snatched a point when referee Alan Muir pointed to the spot for a Ryan McGivern challenge on Gary Mackay-Steven - despite suggestions the foul was outside the box - and Russell converted from 12 yards.
