Seattle Seahawks quarterback Russell Wilson has said that he is not concerned by the team's offensive struggles during pre-season.

The Seahawks' first-team offense have failed to score a touchdown in 12 drives, and five of those have finished without moving the chains at all.

However, the 26-year-old believes that their offence is impressing in practice against "one of the best defences in the NFL" and will be ready once the new regular season begins.

Wilson told reporters: "I'm not concerned, we're not concerned.

"We prepare, we believe better than anyone else and that's how we're going to show up. We believe on Sundays we're going to make something happen."

Seattle will host the Oakland Raiders in their opening fixture a week on Sunday.
