Arsenal have seen a €30 million (£26m/$35.5m) offer rejected for Roma forward Cengiz Under, according to Tuttomercatoweb.
The 20-year-old has impressed during his first season for the Giallorossi, scoring eight goals in 32 appearances.
Though Roma are reluctant to sell, they would want around €50m (£44m/$59m) for the Turkey international, with Monaco having also seen a €35m (£31m/$41.5m) bid rejected.
