Chelsea Champions League winner Ramires believes Arsenal will struggle to keep hold of Gabriel Martinelli.
The Brazil striker is being linked with Juventus in today's Turin press.
Ramires told the Metro: "Martinelli is an amazing player.
"He was absolutely fantastic this season with Arsenal and it's great to see such a talented Brazilian player grow up.
"It is inevitable that big clubs like Real Madrid and Juventus will knock on the door sooner or later."
