Diario Sport cite London-based Metro newspaper that United are considering an ambitious move for the Gabonese international this summer.
It follows on directly from a report last week in Diario Sport that star striker Aubameyang would be willing to force a move to the Camp Nou this summer.
The reports outline how the Gunners would be demanding a fee of €55m for the striker who has been prolific for the club since his January 2018 switch from the Bundesliga, scoring 61 goals in 96 appearances.
It is said by the report that the Blaugrana met with the 30-year-old’s representatives back in January when they became aware of a long-term injury to Luis Suarez.
