Arsenal are reportedly keen on securing the signature of Calum Chambers from Southampton this summer.
The North London outfit are believed to have stepped up their interest in the 19-year-old due to the growing uncertainty over Bacary Sagna's future.
According to the London Evening Standard, an offer of around £10m could be enough for Arsenal to lure the teen to the Emirates, but the Gunners are said to be facing competition from Manchester United.
Chambers signed a new four-year contract at St Mary's last summer.
