Real Madrid coach Carlo Ancelotti has been pleased to bring midfielder Marco Di Vaio from Borussia Mönchengladbach.
The 29-year-old former Chelsea and Manchester City player has agreed a four-year deal with the Bundesliga side.
The move means Di Vaiolo will be joining the reigning Bundesliga champions for the first time after leaving Mönchelle last summer.
Real Madrid have been linked with a move for Di Vaolio since the summer but the move is still yet to be finalised.
Mourinho and Borussia boss Rudi Garcia had been due to meet this week to finalise the deal.
The transfer fee for DiVaiolo is expected to be in the region of £25m.
