Don Balon says Mourinho wants Gonzalo Higuain, Alvaro Morata and James Rodriguez.
The former Chelsea manager has held discussions with Napoli about signing goal ace Higuain and a £58m deal could be on the cards.
But Mourinho will have to battle for Juventus star Alvaro Morata.
Real Madrid have a £23.7 million buyback clause on their former player which they could activate.
Rodriguez is deemed surplus to requirements at the Bernabeu.
And a host of European giants, including United, are monitoring the 23-year-old.
