The former Swedish national team midfielder, who last year was treated in a respirator after suffering several blood clots in the brain, showed up at Sleipner's training on Thursday evening.
However, it is unclear whether the 29-year-old is on his way to a comeback on the football pitch in a match context.
He will train with us today (Friday) too, I know. After that, I don't know more, but it has to be on "Koffe's" terms, says Sleipner's sports manager Calle Svensson to Aftonbladet.
Olsson recently moved back home to Norrköping after agreeing to terminate his contract with Danish Midtjylland.
Sleipner is happy to help him back to elite football.
You can see directly from yesterday that it's an incredibly skilled football player who should play at a completely different level than Division 2, says Calle Svensson.
When asked if Olsson can come to play matches for Sleipner, he says:
It's clear that it would be a dream for us to see Kristoffer Olsson in a Sleipner jersey, that's probably understood by everyone. But that has to come from "Koffe" himself.
