Nwaneri told Arsenal's website: “It means everything to me, I'm so happy to have got it done. This is where I feel at home, and where I’m going to develop the best. I'm ready.
“I’m very excited. I see this as my first real season, and part of a proper squad in the changing room. I'm so excited for what I can bring to the team and how I can help the team.
“I'm a very versatile player, so I think I'm going to play anywhere across the front five, and I’m ready to do what the manager needs.”
