The Â£21million rated Colombian international has been linked with a host of European clubs and a move away from La Liga after playing an integral part in Sevilla's successful Europa League campaign.
The Red Devils were thought to be front runners for Bacca's signature but reports today in the Metro suggest that Arsenal have moved in front of the Old Trafford club
Spanish site Abola (translation required) say that Wenger has previously sent scouts to watch the striker in action.
The Gunners won't have a clear path to Bacca's signature though, with Manchester United still interested in the striker after letting compatriot Radamel Falcao return to AS Monaco and question marks over Robin van Persie's long-term future under Louis van Gaal.
Bacca has scored 28 goals in all competitions this season and has bagged 49 goals in all games since joining Sevilla in 2013.
