Thomas Rogne is anticipating a tough Clydesdale Bank Premier encounter against Kilmarnock at Celtic Park on Saturday.
The Norwegian defender was in the Hoops side which suffered a shock defeat in the Scottish Communities League Cup final against the Ayrshire outfit at Hampden last season but he also experienced the joy of clinching the SPL title at Rugby Park several weeks later.
It is the cup final defeat, though, which acts as a reminder to Rogne for Celtic to be at their best against Kenny Shiels' side.
"Kilmarnock are a good side with some good players and play some good football as well," he told the club's official website.
"We had mixed experiences against them last season but if we play as well as we can, we should win.
"But there are no easy games in the SPL. They are always tough so we need to be really up for it."
Celtic go into the game on the back of an encouraging Champions League display against Barcelona in the Nou Camp on Tuesday night.
It took an injury-time goal from defender Jordi Alba to give the star-studded Catalan giants a 2-1 victory but the performance earned Neil Lennon's side plenty of praise.
"That´s one of the challenges as the Champions League nights are always very special for the fans, players and everyone," said Rogne. "So it´s hard sometimes to go from there and into domestic games but I think we showed against Hearts in the last game that we can deal with it.
"We had a great result in Russia (against Spartak Moscow) and played a good game against Hearts and got the win we needed so we just have to stay focused on the next game as that is always the most important one."
