The young striker returned to action after long-term injury.
"It is always nice to see young players returning that have had nasty injuries. It is good for those two because they might get one or two throughout their careers and they can deal with it if they have been there before. It is not nice but it is great to see them back," Banfield told arsenal.com.
"It is always nice to see someone score in his first game back so we are pleased all around."
