Vasteras SK admit Manchester United's deal for Benfica defender Victor Lindelof has boosted their finances.
VSK were due a percentage of the fee Benfica sold Lindelof for - courtesy of a sell-on clause in the Swede's original transfer.
President Christina Liffner, while refusing to discuss figures, admits the money involved is substantial.
"What lies behind all this is Vigge and those who wrote this 2011 contract, which I do not yet understand why Benfica agreed to it then.
"They had to buy him cheaply, but still...
"That they dared include such a large proportion of the resale - I do not think they believed this was ever going to happen."
