The former Bafana Bafana midfielder re-joined Arrows on a short-term deal in October last year after he parted ways with English Championship side Cardiff City.
The 32-year-old, who scored on his second Abafana Bes’thende debut - against Maritzburg United - has missed the last six PSL matches after suffering a calf strain at training.
And with post-season attentions turning to the transfer window, Larsen admits he is in dark over Dikgacoi’s continued presence at the Durbanites, and that he will have to leave that in the hands of Arrows' chairlady Mato Madlala.
"The chairlady [Mato Madlala] will decide [Dikgacoi’s future]. He came on a short-term contract, as far as I know," Larsen tells KickOff.com.
"He's been plagued with injuries and he had an operation in December on his knee and now he had the calf pull about a month ago that had kept him out for the last three to four games so he's had issues with injuries.
"But that [whether he remains next season] is up to the chairlady to decide. I think she runs the club how she sees fit and she's done a good job in running the club the way that she does and we'll just support every decision she makes."
Meanwhile, Larsen, whose side clinched a 2-1 win over Orlando Pirates on Saturday in the final league game of the season to secure the club's first top-eight finish since 2009, says he's somewhat disappointed that he was unable to get the most of out the veteran Dikgacoi this season.
The former Fulham midfielder featured in just 10 league matches, failing to see through the full 90 minutes even once.
"We’d have liked to get more out of him but unfortunately those [the injuries] are the things that kept him from giving us the performances we hoped for," he added.
"But the one good thing was his presence at the club and his professional attitude; he was a great pleasure to work with. I think the young players, in particular, looked up to him and he's always giving them advice as well.
"But just his present at the club was a positive thing for us and, like I said, he's role model and very, very, very good professional. I think the players learned a helluva lot from him."
Malawian striker Chiukepo Msowoya is another player whose future is set to be decided after he joined the club on the short-term deal from NMC Big Bullets in his homeland in January transfer window.
