Roma chief Walter Sabatini is shopping in Mexico for a new defensive signing.

Sabatini is keen to add a new defender to Roma's squad in January.

The Roma director is watching Monterrey youngster Cesar Montes.

The 18 year-old is a first teamer in Mexico's top division and Sabatini's scouts are monitoring him.

Montes wears the number 286 on his Monterrey shirt.
