Arsenal chief Raul Sanllehi had a scout posted on Sunday to see AC Milan defeat Cagliari.
Milan won 3-0 and in attendance was a high level Gunners scout, reports TMW.
Several players were of interest, with Cagliari midfielder Nicolo Barella high on Arsenal's agenda.
Also suggested as a potential target was Milan attacker Suso.
Both players are under consideration at the Gunners after they failed to strike a deal with Inter Milan for Ivan Perisic last month.
