Rangers and Celtic met in the first Old Firm game of the season at Ibrox this afternoon as the Hoops extended their gap over their bitter rivals to eight points at the top of the Scottish Premiership with a 2-0 win.
Second-half goals from Tom Rogic and Leigh Griffiths sent Pedro Caixinha to his third Old Firm defeat in three attempts.
Celtic controlled the frenetic early stages as they looked to get off the mark quickly and managed to win two corners in the first few minutes.
Brendan Rodgers' side kept their hosts pinned back for spells but Rangers' defence coped fairly well with any danger.
Referee Craig Thomson had a big call to make after 13 minutes when Celtic's Jozo Simunovic brought down Alfredo Morelos in the box but the referee somehow saw nothing in it and waved play on.
The Gers grew into the game as the first-half progressed and more than matched their bitter rivals as they tried to record their first Old Firm win since April 2015.
19-year-old defender Ross McCrorie looked solid on his full debut, dealing with Leigh Griffiths well and restricting the Scotland striker's chances at goal in the first 45.
Five minutes into the second-half Tom Rogic fired Celtic in front after latching on to a loose ball in the Rangers penalty area and lashing the ball high beyond Foderingham.
Rangers immediately threw everything at getting back into the game and Craig Gordon pulled off a fantastic reaction save from Alfredo Morelos' point-blank header.
Celtic grabbed a second on 65 minutes when Leigh Griffiths broke through Rangers' defence and blasted a low shot in at Foderingham's near post.
The hosts continued to push forward looking for a way back into the game but Celtic comfortably managed to see the game out - spurning a few chances to extend their lead - and take the three points.
