Rangers beat Celtic again to cut Premiership lead to two points

Ryan Naderi's strike gave Rangers their second win against Celtic in eight days to move within two points of their Old Firm rivals at the top of the Scottish Premiership.

Martin O'Neill had insisted Celtic's confidence was not "rock bottom" after their League Cup defeat at Ibrox was followed by a loss to Ferencvaros in the Europa League. But, in front of 60,000 of their own supporters, it certainly took another huge dent.
