The Manchester City star has stressed that it is all or nothing ahead of Spain's clash wtih Italy on Sunday but is confident that his side have what it takes to win
The finalists drew 1-1 on June 10 before going on to qualify ahead of the Repubilc of Ireland and Croatia, but the Manchester City man insists there is a lot more pressure ahead of their next showdown in Kiev.
"The first match with Italy here was tricky, but this one is not quite the same, mainly because it’s a case of win or bust," Silva was quoted as saying by fifa.com.
"Ahead of the group-phase match, both teams knew that a defeat wouldn’t eliminate us. Of course, now the situation is very different, just as the game will be."
The 26-year-old also revealed that La Roja are brimming with confidence ahead of the game, but acknowledged that they can still improve in certain areas.
"There’s no doubt that Italy are extremely tough opponents, but when you reach a final, that’s to be expected," he added.
"We’ve played Portugal and France, two top-class teams, and we managed to overcome them both. The objective has obviously not changed, and our confidence is as high as it’s ever been.
"We’ve been working flat out to reach the final. To have achieved that goal means that we’ve clearly been playing at a high level, but if we want to be favourably compared with past teams, we need to win; that much is obvious. If we do it, it’ll be historic, but we still have to improve on a few things."
Sunday's showpiece in Kiev kicks off at 20:45CET.
