Norwich striker Simeon Jackson knows the Canaries must be clever to compensate for losing the element of surprise in the Premier League this season.

City face European champions Chelsea this weekend aiming to pick up their first top flight win of the new campaign as they bid to build on an impressive debut year. Both the Canaries and fellow promoted rivals Swansea proved the doubters wrong following their elevation from the Football League 12 months ago, but Jackson accepts Chris Hughton's men face a much tougher task to try and emulate that success.

'The shock factor has gone. We're no longer the surprise package,' he said. 'People know what we're about now and come up with game plans to stop us, so we just have to make sure we keep doing what we can to win as many games as possible.

'I think the ambition is still the same, which is to stay in the league. It's paramount, so you approach games like you always have done, trying to get a result. A lot has been made about struggling to score goals and I don't think we have to change too much. We've been creating chances as much as we always have done. We have to maintain that and it will turn and they will go in.'

Jackson's strike partners Grant Holt and Steve Morison got off the mark against Liverpool, after the Canadian opened his Premier League account to earn a home point against QPR last month. The 25-year-old insists City's frontline remain confident in their ability to produce at this level.

'You don't worry about what others might say,' he said. 'You just focus on doing what we're doing. We've looked good at times, we're creating chances and it's the most important thing. Like I said we just have to maintain what we're doing and it will turn and we'll start getting results.

'It's a new regime but at the same time the gaffer has come here and done well. He's kept the core of us together and the same mentality in how we approach games. There hasn't been that much of a change and the lads go into every game thinking we can get a result.'

Jackson has looked sharp during City's otherwise difficult start to the league season, which also included a recent transatlantic trip on World Cup qualifying duty for the Canucks.

The Canadian international will head back across the Atlantic after Saturday's Premier League trip to Stamford Bridge for fresh qualifiers against Cuba and Honduras, and Jackson is happy with his own form for club and country.

'It's been okay,' he said. 'Unfortunately we haven't had that first win yet but it will definitely come. I haven't done anything different really (over the summer). I had some games for Canada and tried to keep the momentum going and did some work in the off-season in the one-week break I had so I could come back ready to impress the new manager.'
