A goalkeeper Jansson trusts
Olsen, 27, played with Jansson in the youth set up at Swedish giants Malmo, and again for two years between 2012 and 2015.
The duo have also played together in the yellow and blue of Sweden’s national side, striking up a partnership that has seen them connect well when 6ft 5in colossus Jansson plays in front of his close friend.
Now, the defensive stars should combine together for a third time under manager Christiansen in what could be the key partnership that pushes Leeds towards Premier League promotion for the first time since their collapse in 2004.
