The Brazilian star was part of the Magpies' side who earned a comprehensive victory over Unai Emery's side at Villa Park, a result that ends a four-match losing run in the Premier League.

With a £100million release clause in his contract, Newcastle could be powerless to keep him and that means that they perhaps must enjoy him while he's still around.
His post-match social media post suggests he's more than happy to stay though, saying: "Two happy years in this team, with a very important win! Thank you for everything, @NUFC fans. I'm happy here!"
