Mikel Arteta said on Friday Arsenal could sign a replacement for Nicolas Pepe after the Ivory Coast winger left the Premier League leaders to join Nice.
Arsenal has been linked with a move for Wolves winger Pedro Neto and Arteta admitted he could adapt his transfer philosophy after prioritising early deals for Manchester City duo Gabriel Jesus and Oleksandr Zinchenko at the start of the window.
"We have done it in a different way. At the start of the window we signed players before getting other players out," Arteta told reporters.
"Now we have done something different, we have let a player go and maybe we'll be able to recruit somebody.
