Gomez can become Sunderland's Cesc Fabregas.
That's the verdict of one-time Black Cats midfielder Arnau, who spent two seasons as a team-mate of Gomez with the Barcelona B side.
"I know Jordi well from playing alongside him at Barca," Arnau told the Evening Chronicle.
"He's a very good player who will never stop running and working in midfield. He can tackle and deliver set-pieces, but I think his best quality is his creativity - his final pass.
"Don't get me wrong, he's not Fabregas or Iniesta! They are special, world class players.
"But Jordi could play a similar role within the Sunderland team, providing the pass that gets through a defence."
