David Silva: Criticism can be undeserved, I've been here for 12 years and I'm used to it World Cup 2018 - Spain vs Russia Recognised that Spain haven't been at their best

Spain have not been convincing in Russia for the World Cup this summer, with Manchester City's David Silva one of those to face the most criticism.

The playmaker has not been at his best but dismissed the importance and influence of negative coverage affecting him and his teammates.

"There's been a lot of talk about the criticism, we're professional and have to dedicate ourselves to playing and changing opinions," he insisted.

"Sometimes the criticism isn't deserved, I've been here for 12 years and I'm used to it.

"The first and second games were good but the opposition count too, the group was tough and we have to minimise mistakes.

"We have to all be focused and defend well, at a World Cup the smallest thing can send you home."

Reflecting back on victory at Euro 2008, Silva pointed to the style which proved so successful then.

"What has brought us success has been having the ball, then the game demands different things of you," he explained.

"We have to know how to do it, our philosophy has taken us victory."

The former Valencia man also refused to underestimate Sunday's opponents, Russia, making it clear that they will be treated the same as any other nation.

"Any opponent is tough, it takes a lot to win," said Silva. "Russia will be very difficult and it will be the same as if we were playing against Brazil."

Silva is one of those battling for a spot in Fernando Hierro's team.
