And on Thursday night the Gunners will be looking to take another step closer to sending Arsène Wenger off in style when they take on Atléti in the first leg of their semi-final.
This week has brought about the beginning of the end of Wenger's reign at the Emirates after 22 years, as it was confirmed the Frenchman is set to leave the club in the summer.
And he will go into this week's huge game with a striker full of confidence after Alexandre Lacazette scored two goals following his return to the side on Sunday against West Ham.
With Pierre-Emerick Aubameyang cup tied, it couldn't have come at a better time for the centre forward, and our unique algorithm has, as expected, selected him up front against Atlèti.
