Arsenal will face competition from London rivals Tottenham in the race to sign Rafinha from Barcelona this summer.
Sport, as cited on Calcio Mercato, claim that Spurs have now expressed an interest in the player.
Inter are also in the hunt to sign the player after he impressed whilst on loan at the San Siro in the second half of last season.
After qualifying for the Champions League, Inter are looking to strengthen their squad and add quality in important areas.
The Gunners have been linked with a move for the Brazilian, with Unai Emery said to be a fan of the player.
His long-term future appears to be away from Barcelona after falling out of favour at the Nou Camp, which resulted in him leaving on loan last season.
Spurs themselves are looking to deepen their squad ahead of the new Premier League season in a bid to build on their third-place finish.
