Gabriel Paulista has joined Valencia for an undisclosed fee, Arsenal have announced.
The Sao Paulo-born defender made a total of 64 appearances for the Gunners following his arrival from Villarreal in January 2015.
Gabriel Paulista had fallen below Rob Holding, Laurent Koscienly, Shkodran Mustafi and even usual left-back Nacho Monreal in the centre-half competition.
Gabriel started his career with Brazilian club Vitoria before moving to the Yellow Submarine in Spain.
He joined the Gunners just two season ago, with Wenger desperate to sign a centre-back.
Gabriel will be reunited with his former Villarreal coach Marcelino and told reporters: “I’m very happy and delighted.
“I’ve spoken to Marcelino on several occasions and I know his method of work.”
Gabriel has become Valencia’s third summer arrival following the signings of Serbia international midfielder Nemanja Maksimovic from Astana and Brazilian goalkeeper Norberto Neto from Juventus.
