Arsenal already have an agreement over personal terms with Viktor Gyokeres but are also pushing to sign Benjamin Sesko from RB Leipzig.
Sporting striker Gyokeres is one of the most in-demand players across Europe following an obscene 54-goal, 13-assist season for the Portuguese champions.
But per Belgian journalist Sacha Tavolieri, Arsenal are negotiating with Leipzig over Sesko as they seek to make progress in talks with multiple players.
That is so they are not left on the backfoot if talks with Sesko or Gyokeres backfire.
