Valencia attacker Nani hailed "special" Lionel Messi ahead of his side's clash with Barcelona on Saturday.
The Oranges host Luis Enrique's side - who smashed Pep Guardiola's Citizens 4-0 on Wednesday night in the Champions League - at the Mestalla as Valencia look to climb up the La Liga table.
However, Nani recognises the threat Messi posses after the Barca star scored four times in two games since his return from a groin injury.
"Messi is a special player and few compare," he said as Goal.com quoted.
The former Manchester United winger Nani also praised his Portugal team-mate Cristiano Ronaldo.
He added: "We know we have Cristiano, contesting all year the Golden Ball with Messi.
"But it's not until the end that we know who is the best in the world."
