Jussi Jaaskelainen believes Norwich City could decide that attack is the best form of defence in Saturday's Barclays Premier League fixture.

The Canaries welcome West Ham United to Carrow Road having been beaten 7-0 at Manchester City last weekend. In their last five matches in all competitions, Chris Hughton's side have conceded 18 goals, scored just two and won none of them.

While Norwich have struggled as late, Jaaskelainen has warned his team-mates that the wounded Canaries could spring out of the blocks.

"Everyone knows that when a team loses a game like that, the reaction is going to be massive from them, so it might be the worst time to play them," said the No22, who has conceded just one goal in five away league matches so far.

"We need to stop them early on because I think they will come out all guns blazing in the first ten or 15 minutes. After that, we need to keep the home crowd quiet and play our own game away from home the way we've been playing."

Jaaskelainen could come up against a familiar face in Norwich's Sweden international and former Bolton Wanderers striker Johan Elmander.

"Hopefully we can keep a lid on him. I've trained with him for three or four years, so it will be nice to see him and play against him. Hopefully I'll have the advantage because I know his game, but who knows?"

Jaaskelainen will hope West Ham can produce a similar performance and result to the one they produced in their away game at Tottenham Hotspur. There, a fantastic defensive performance and display of counter-attacking football scored the Hammers a 3-0 success.

"The Spurs match was one of those games when nobody expected us to go there and win. That helped us to go there and play more relaxed and we obviously we used our chances really well in that game and it gave us a great win for us and our fans."

One player who was key to the win at White Hart Lane and will be important again at Carrow Road is England U21 midfielder Ravel Morrison - a player Jaaskelainen rates highly.

"He's really come in this season like a new man after having a great experience on loan, where he learned a lot. He is now starting to show the talent that he has. He has been brilliant for us and has hit the level we expected of him. As long as he looks after himself well, I think he will be a very good player for us for a long, long time.

"I don't think he knows what fear is yet. He is a young boy and we're just hoping he can keep his level up and keep performing as he has done so far, because he's been really, really good."

Morrison has also played his part defensively in recent weeks and West Ham will need to be solid, organised and concentrated at Norwich, despite the fact their hosts have netted just four goals in five home league matches so far.

If they do get through the Hammers' rearguard, Jaaskelainen is prepared to stand tall as the last line of defence, as he has done so often in his time at the Club.

"Our defensive strength is coming through the team. When we set up, we make sure we try to keep a clean sheet because that gives you a very, very good opportunity to go and win a football match. We've been working hard out there with the back four and I think we've done pretty well so far.

"The main thing is that we go out and try to get the three points and get the win and obviously it's my job to help the team whenever they need me. At the end of the day, it's all about results."
