Mikel Arteta might settle for a make-shift attack using Nketiah or Gabriel Martinelli alongside Bukayo Saka.
Yet, a surprise hint was given to the English club when Portuguese winger Rafael Leao who plays for AC Milan.
When asked about playing in a new league, he told radio station RDP Africa: "Yes, in the future…
"But now I'm 100% focused on AC Milan — it's a top club and I'm under contract there."
Arsenal and Chelsea have been linked with Leao and he added: "I watch many games. This year, I like Arsenal — they're playing very well."
Leao still has 18 months left on his contract and leaving UEFA Champions League team for an Europa League team seems unlikely but during the summer, he might make the move.
