The Celtic duo were on hand to watch their bitter rivals lose in shock fashion at Falkirk.

Celtic boss Ronny Deila and his assistant John Collins were in attendance at Falkirk on Friday night for reconnaissance ahead of next month's Scottish Cup semi-final with Rangers.

It looked set to be an unpleasant night for the Bhoys duo early on as Mark Warburton's side - who were 14 points clear at the top of the Scottish Championship at the time - raced into a 2-0 goal lead inside 10 minutes.

However, goals in the last 18 minutes from Blair Alston, Myles Hippolyte and Robert McHugh stunned Rangers as second-placed Falkirk reduced the deficit to 11 points with a fine comeback.

Celtic fans will be hoping that the pair picked up some tactical information on their bitter Old Firm rivals, whom they face at Hampden Park on April 17.

For under-fire Deila, defeat simply is not an option if he harbours genuine hopes of retaining his job beyond the summer.

The Hoops are making tough work of what should have been a one-horse race in the Scottish Premiership, with Aberdeen just one point behind them as the campaign enters the final stretch.
