Marc Overmars had claimed that the Eredivisie boss had been offered €6 million a year to run the Russian club, but Spartak's caretaker coach laughed off the suggestion
The Dutch side's sporting director Marc Overmars told De Telegraaf that De Boer had been offered the head coach role, with a figure of €6 million a year mooted.
Karpin has taken temporary charge of the Russian club ever since Unai Emery's sacking in November, and he laughed off the suggestion that De Boer had been offered the job permanently.
"I was surprised by the news that I, as general manager, contacted Frank de Boer for the job," Valery Karpin told SovSport.
"To that alleged salary proposal I could only smile. Let's be clear about this: De Boer has never been approached by anyone at Spartak Moscow."
The Russian club were recently knocked out of the Champions League having been in the same group as Barcelona, Celtic and Benfica.
