Brazil international Neto has joined us from Bournemouth on a season-long loan.
The 35-year-old has made 63 appearances for the Cherries since joining them in August 2022 and was named club captain just six months later.
After signing for us, he said: “I’m realising a dream in my life, a dream come true, and I’m really, really happy.
“I had two dreams as a kid to play for a football team. It was my team in Brazil, where I grew up and became a professional footballer, and also Arsenal. And now I’m realising it! I’m a really lucky person.
