The Gunners swooped for the Brazilian starlet in January 2010, acquiring his services from Fluminense.
Arsene Wenger made his move in the understanding that Silva would be granted a visa by FIFA, but no paperwork was processed.
Arsenal have therefore been forced to send the highly-rated forward out on loan - with spells taken in at Spanish outfits Levante, Alcoyano, Ponferradina and now Murcia.
Silva believes he will shortly be granted a European passport, freeing him to stake a claim for a place in Wenger's plans for 2014/15.
He told Lancenet: "The process to the get the passport is already under way.
"The Spanish law says that to request the documents you have to have been here two years. In January 2014, it will be three years so I think they will be ready.
"The pre-season in England starts in July and I'll have a passport by then.
"I hope to have the opportunity to achieve my dream of playing for Arsenal. The team is strong and I hope to fit in well."
Last I heard he was munching through a mountain of pizzas. Heaps of talent - appalling attitude. I doubt very much we will see him at the Emirates.- popularpete
