Ozil is still to agree a new contract with Arsenal - his current deal is due to expire in 2018 - and his future has therefore been the subject of much speculation in recent weeks and months.
An approach from Barcelona would be particularly controversial considering the player's previous ties with Real Madrid, with whom he spent three seasons between 2010 and 2013.
According to El Confidencial, Barça have made it clear that Ozil is seen as a good fit for their ongoing plans. It is suggested that the reigning Spanish champions' brazen approach to transfers and going over the heads of clubs, and sometimes even agents to talk directly to players, could also come into play once more.
The Spanish report additionally makes note of Bayern Munich's apparent interest in Ozil. The 28-year-old hasn't played for a club in his home country since leaving Werder Bremen shortly after the World Cup in South Africa, but a move to Bayern would see him return home.
Elsewhere, Julian Draxler has named Ozil as the German international team-mate he would most like to have join him at new club Paris Saint-Germain.
The pair are firm friends and it was rumoured prior to Draxler's move to France last month that Ozil has been involved in the alleged Arsenal attempts to land the 23-year-old winger. Now, however, the shoe seems to be on the other foot.
"There is one but I'm afraid it will get me in trouble if I say it. I'd like to see Mesut Ozil [at PSG]. He can play in any team in the world. So if he wants to come, he will be welcome from my point of view," Draxler told beIN Sports.
