Arsenal has made Emerson Royal a transfer target as they prepare for the departure of Hector Bellerin in the summer.
The Gunners have been served by the Spaniard since 2011 when they poached him from Barcelona.
He is now set to look for a new challenge, according to Sun Sports.
If he is eventually sold as expected, he would need replacing and Emerson is one of the players Arsenal is targeting, according to Mundo Deportivo.
The Brazilian is currently at Real Betis where he has spent the last two seasons, but he is co-own by them and Barcelona who can buy his full rights for just £2.5m in the summer.
The Catalans already have Sergi Roberto and Sergino Dest as their first choice right-backs and can do without him.
They are also hundreds of millions in debt and would want to raise money from the sale of some of their players.
They will make some good money from selling Emerson, who has also attracted the attention of Tottenham.
If Arsenal cannot sign him, the Sun Sports report claims that they would try to sign Norwich’s Max Aarons who has also been on their radar for some time now.
