Arsenal are still pondering a January loan deal for teenage prodigy Marquinhos.
However, the Brazilian will only be allowed to leave if Mikel Arteta signs another winger, according to The Sun.
The 19-year-old scored and assisted on his debut in last week’s Europa League win over FC Zurich.
Arteta will weigh up whether a loan move would be more beneficial for Marquinhos when the January transfer window rolls around.
Marquinhos will be dependent on Europa League and domestic cup appearances to gain senior experience with the North London club.
