Manchester City are lining up a January move for Espanyol full-back Aaron Martin,according to Spanish source Sport.

The 20-year-old left-back has been impressive for Espanyol this season, and the report suggests that City have been scouting him for some time.

The Citizens suffered a huge blow when they lost summer-signing Benjamin Mendy to a long-term injury last month, but they have already started looking for replacements.

The French left-back has been ruled out for a minimum of seven months after rupturing the anterior cruciate ligament in his right knee.
