Two goals from teenage debutant Tony Watt guided the Scottish Premier League champions Celtic to a 3-0 win at Motherwell and put a dent in the home side's Europa League aspirations.
Watt, 18, came off the bench just before the hour with the score at 0-0 to break the deadlock with two goals in three minutes. Captained by Gary Hooper, Celtic played with a much-changed side and were thankful to stand-in keeper Lukasz Zaluska for keeping the score goalless up to half-time before Watt struck. Cha Du-Ri headed Celtic's third late on.
The threat of relegation lingers for Hibernian after they lost 1-0 at home to Kilmarnock, and also lost top-scorer Gary O'Connor to a foot injury.
Former Hibs player Dean Sheils struck the decisive blow against his old club just before half-time with a well-placed penalty to leave the Edinburgh side six points clear of bottom-placed Dunfermline, with four games remaining.
On Saturday, Rangers comfortably won 3-0 at Hearts, with Andrew Little netting either side of half-time after Sone Aluko had opened the scoring.
