Unai Emery is claimed to be working on completing the addition of a new defender in the January transfer window to bolster his options within the squad.
The former Paris Saint-Germain manager has made a decent start to career at the Emirates stadium which has seen his new team put together an unbeaten run of 16 games across all competitions.
Injuries to key players have remained a problem for Emery and the Arsenal boss appears to be chasing the signing of a new full-back to improve his defensive options.
According to reports as of Thursday, the Gunners are now in advanced talks to agree the signing of Emerson Aparecido Leite de Souza Junior, who is commonly known as Emerson.
The 19-year-old is one of the hottest prospects at his current club Atletico Mineiro, and the Gunners are reportedly edging closer to move which would see him complete a north London switch in January.
