The Selecao captain has tipped his international team-mate to have a big impact when the World Cup kicks off in June
The 21-year-old forward has become an integral part of the national team since his debut in 2010, scoring 27 goals in just 46 games, while he was also the star of the tournament at last summer's Confederations Cup.
His early months at Barcelona have provided glimpses of his ability following a big money move from Santos in the summer and his compatriot is convinced he has the quality to light up the World Cup.
Speaking to Telefoot, Silva commented: "Neymar can save us. I had no doubt about his success in Barcelona, he has surprised the Spanish press. He brings a lot offensively and is a great player."
Neymar is widely considered to be Brazil's most potent attacking weapon and the pressure on him and his team-mates will be huge as Brazil seek to win their sixth World Cup on home soil.
Despite the immense pressure Silva admits he cannot wait for the tournament to begin.
"There is not a day I wake up and do not think of the World Cup. This is a moment that is constantly in my head. Until the day of the final, it will be like this. The confidence in the national team has returned. The people believe again in the Selecao. This is a special purpose and it is a big responsibility."
Finally, the PSG defender also gave his backing to club team-mate Lucas Moura, who is battling to cement his place in the squad.
"I hope that Lucas will be with us at the World Cup. I work every day with him, and I see him working very hard in training. But there is one person who decides and it is Scolari."
