Arsenal boss Unai Emery has reportedly identified Torino defender Nicolas N'Koulou as his one and only January transfer target.
The Gunners conceded their 31st goal of the season in Tuesday's 4-1 home win over Fulham - more than they ever shipped after 21 games under former boss Arsene Wenger.
Emery is happy with his attacking players, but Calciomercato reports that a new centre-back may be brought in to toughen up the backline, with N'Kolou on Arsenal's radar.
Torino are said to be keen to keep hold of the Cameroon international, however, meaning that the North London outfit may have to spend big to get their man.
Sokratis Papastathopoulos was signed from Borussia Dortmund for a reported £17m in the summer, though he is one of a number of defensive players to have struggled in the first half of 2018-19.
