Marshall hopeful of a crying game from Larsson on Saturday
The Swedish striker broke down after playing his final competitive match at Parkhead on Sunday and this weekend faces his last competitive game for Celtic in Scotland.
It has been a thrilling seven years in Glasgow and his team-mates are determined to give him a glorious send-off by beating Dunfermline to complete a league and cup double.
"Hopefully we can win it for him," said Marshall, "We hope for tears of joy as well, this time.
"He was quite emotional on Sunday but he half expected to be like that because I know how much he loves the club.
"This is a special game and that's why the boys really want to win this one he deserves it for his time here."
"He will be sadly missed," continued the 19-year-old Marshall. "I supported the club, so it was great to play alongside him.
"At the start of the season I thought there was not much chance of that but I've come in and played quite a lot.
"He has been an unbelievable player and he will be impossible to replace, but life goes on after others."
That has been the case for Marshall this season in a remarkable rise to prominence which will end with a Hampden Park final.
In the UEFA Cup, he was thrown into the deep end in the Nou Camp after first-choice keeper Robert Douglas was sent off in the first leg but he produced a stunning display to prevent Barcelona from scoring.
Again the Scotland goalkeeper is absent after undergoing surgery but, while Marshall expressed sympathy for the veteran, he is determined to make the most of his good fortune.
"This season's been unexpected and the praise has come since the Barcelona game because it was in the Nou Camp.
"I had just to get on with it and concentrate even more in the bread-and-butter games and in training.
"I am always nervous before games and there is always pressure on me to perform. This is the Scottish Cup final so I am expected to be nervous but I'll treat it like a normal game.
"It's a real shame for Rab and he's obviously been carrying the injury for a while but I have done well."
Marshall will come up against an experienced Dunfermline strikeforce of Craig Brewster and Stevie Crawford; Marshall rates the pair as one of the best partnerships in Scotland, which is worrying as both missed the Fife club's recent victory at Parkhead in the league.
"Obviously Stevie Crawford has played a lot of games for Scotland and I think, had it not been for Brewster's age, he would have been there as well," said Marshall.
"Behind us they are in the best two or three strikers in Scotland so we know it's going to be a hard game."
