Mikael Lustig is desperate to avoid being on the end of an upset when Celtic travel to Stranraer in the fourth round of the Scottish Cup.
The former Rosenborg defender has experienced disappointment in the green and white when Morton defied the odds in the League Cup at Celtic Park back in 2013.
But it’s the memories from his stint with the Norwegian club which really stings that will be in the back of his mind when the Hoops begin their quest for silverware in the competition they have won 36 times in the clubs history.

With Rosenberg chasing the double in 2010, Norwegian second division minnows Follo came from 1-0 down to win in extra time and cause a major upset, which is something the 29-year-old doesn’t want to experience again.
As quoted by the Glasgow Evening Times, he said:
I had a big one when we lost at home here to Morton. That was quite a big shock. But the biggest one was when I played for Rosenborg in the Norwegian Cup semi final.
We faced a team called Follo, who were bottom of the second division and we lost. It was a massive opportunity to win the double and we didn’t do it.
We got off to a good start, scoring the first goal and we probably thought the game was over. But they scored a wonder goal in the last minute to take it to extra time and then we lost in extra time.
The fans weren’t happy. We had one game to get to a final and Rosenborg had not won the double for many years, so that was a real big opportunity. It was tough.

Stranraer last clashed with Celtic in 2001, the Hoops coming out on top in a 4-1 win at Stair Park.
With Lustig eyeing up a domestic sweep of trophies this season, the Swedish international is determined not to take Brian Reid’s men lightly and wants a professional approach to avoid disaster.
We are big favourites but we if we don’t go in with a 100 percent attitude then it can be hard
We have to treat it like a normal game. The coaches have had a look at them and we will have a look at them tomorrow morning.
Of course, we can win a treble. We are favourites in all competitions and there are still plenty of games to go. You can see what can happen – a referee can make a mistake and everything can change. We can do something wrong as well, There’s a long way to go but we are aiming for that.
