Porto defender Ricardo Pereira has reportedly emerged as a transfer target for Arsenal.
Pereira is currently on loan at Nice, who he has helped to first position in the Ligue 1 table, and his performances in France are said to have alerted Arsene Wenger.
According to the Daily Star, the Gunners boss is looking for long-term competition for Hector Bellerin and, with Carl Jenkinson and Mathieu Debuchy out of the picture at the Emirates Stadium, Wenger is assessing potential targets.
That has led him to the 23-year-old Portugal international, who can also play on the wing and has featured 47 times for Nice.
Pereira is said to be valued at £20m by his parent club, despite failing to make much of an impact at Estadio do Dragao before his temporary switch to Nice.
