The Argentina international has been on target in each of his last four appearances versus the Gunners, and is available at 10/3 (4.33) with bet365 to extend that streak by opening the scoring at Wembley.
Having found the net in each of the previous two rounds in this competition, 8/11 (1.73) actually appears relatively solid value on him adding to his career total of seven goals against this opposition.
With Gabriel Jesus still a doubt, Raheem Sterling may be required to maintain the prolific form that has seen him score 20 goals already this campaign and there are odds of 6/5 (2.20) available on him coming up with the goods.
However, Leroy Sane’s record in this season’s competition reads three goals in three starts, making odds of 7/4 (2.75) look rather generous on him adding to his own tally of 11 in total.
Aubameyang on form
At the other end of the pitch, Pierre-Emerick Aubameyang is priced at 11/2 (6.50) to really announce himself to the Gunners faithful by breaking the deadlock in this final.
In the absence of the injured Alexandre Lacazette, Danny Welbeck is on offer at 21/10 (3.10) to take his chance by scoring just a third goal in 23 fixtures in all competitions.
