The Hoops have endured a remarkably long season which began back in July and has so far taken in 58 competitive matches, leading the Swedish defender to believe that perhaps there could be some fatigue among Neil Lennon's squad for the Hampden showdown with Hibernian on Sunday.
"We know there is a lot of games involved and you have to try and be alert in your head," said Lustig who is looking forward to some sort of break this off-season.
"The manager has given a few of the boys time off and that was the right move. We need to have a rest mentally, time to not think about football.
"Some of the boys will only get three weeks off and then it will be 11 months of football again. That's a lot.
"I'm away with Sweden after the cup final. We play Austria away and the Faroe Islands at home in the World Cup qualifiers. It's another three weeks before I can rest but hopefully I can handle that.
"Hopefully we will have a strong squad next year so I don't think I will have to play 60 or 70 games next year."
