Mourinho gave Karanka his management launching pad at Madrid.
And the Spaniard told Record: "When I spoke to him and knowing him I know he will go to an ambitious club which can win titles.
"I see him in a project to win, not to make money.
"It will be a club that wins, as Mourinho has always done in his career."
Mourinho has been out of work since being sacked by Manchester United in December.
