Real Madrid defender Nacho is interesting Roma coach Jose Mourinho.
Mourinho is in the market for a new centre-half ahead of the January transfer window.
La Gazzetta dello Sport says Mourinho wants up to five new additions made over the winter market: two midfielders, a centre-half, a fullback and a striker.
For centre-half, Mourinho is keen on Nacho, who has battled for a regular start this season.
The pair worked together when Mourinho was in charge of Real Madrid.
