After missing out on Julian Alvarez from Atletico Madrid, Barcelona have switched their attention to a more experienced striker in Jesus who has been pushed aside by the Gunners.
At 29 years old, Jesus has been training alone, away from the Arsenal squad as manager Mikel Arteta makes it clear that he has no future in North London.
The Brazilian forward has slipped down the pecking order, with Kai Havertz and Viktor Gyokeres preferred up front by the Spaniard, who is focused on defending his Premier League title.
Jesus scored six goals in 27 appearances in all competitions last season, and his experience not just with Arsenal but also at Manchester City has attracted Spanish giants Barcelona.
As per Fabrizio Romano, Barcelona have agreed a deal in what is a fast-moving saga for the Brazilian international.
Jesus was left out of the Arsenal squad for both of the club's first two competitive fixtures this season and after being deemed surplus to requirements, he will be packing his bags for Barcelona.
