Arsenal are watching Callum Hudson-Odoi's progress at Bayer Leverkusen.
The Guardian says Hudson-Odoi has emerged as a shock transfer target for Arsenal.
The Gunners are tracking the winger.
Hudson-Odoi is currently on loan at Bayer Leverkusen from Chelsea.
The 22-year-old is thought to be unlikely to stay at Stamford Bridge in the next transfer window.
Chelsea need to sell this summer to balance the books, and with his deal expiring in 2024, the winger is a prime candidate to go.
