At odds generally ranging from 50/1 to 66/1 a 5-1 scoreline seemed the most popular prediction among Celtic fans backing their team to put the magic hat back in his box.
Winning 4-0, 4-1 or 5-0 was also a popular bet but 5-1 was the favoured scoreline with plenty of fans having extra cash in their account for a weekend of celebrating or to be converted into euros for the trip to Barcelona.
On twitter plenty of fans were keen to show off their winning coupons although there was some disappointment with one fan sticking his wedge on an 8-0 victory.
Armstrong wouldn’t have been aware of the extra joy that his goal brought but the former Dundee United midfielder was delighted to make his mark again on the first team.
He told the Evening Times: “It feels like an entirely different Celtic team – different mentally, different physically, different tactically and all for the better. Everyone wants to be a part of it.
“I have a clear picture ion my head of what I need to do. That last half hour in a number 10 position was fantastic for me and something I really enjoyed. The goal was the icing on the cake.
“That is where I am most comfortable. Hopefully people can see that. It is where I enjoy football the most, it is where I think I make the best contribution. So it is just about taking chances when I get them.”
