Paul Lambert insists Norwich City will not be overawed by Saturday's daunting Premier League trip to champions Manchester United.

The City boss labelled this weekend's pending Old Trafford date as the ultimate test after City moved into the top 10 with an impressive 2-1 Carrow Road win over Sunderland.

'I knew before the game if we could just win this one then we go to Old Trafford with a bit more faith and feeling a bit more buoyant rather than going up there and worrying about getting turned over,' said Lambert.

'I hear people say go and enjoy it but you can only enjoy it if you go and can hold your own.

'In my view, Manchester United are probably the best team in Britain at the minute and along with Barcelona one of the best teams in Europe.

'That is the magnitude of our achievement in getting into this league. No-one is going to expect us to win anything there.

'The lads will love the atmosphere and the stadium and we'll go up there and give it everything we've got.'

Lambert believes his men are learning fast after drawing parallels between the latest Black Cats' win and City's opening home league draw against Stoke. Kieran Richardson's late lifeline set up another tense finale, but this time there was no repeat of the Potters' stoppage time equaliser.

'That is what happens when a team scores with five minutes to go and it puts you on the back foot, especially in this league when you are up against the quality of player you face every week,' he said.

'It is really, really tough and you know for a mistake that you will get punished at this level. I'm delighted that the lads saw it through and even more so when you see us finishing with ten men.

'It was the same at Stoke, which is another game we should have seen through, but I am delighted and we deserved to win again. That first win at home is big step. We're new to it but we're playing really, really well.'

City striker James Vaughan was poised to undergo scans yesterday to discover the extent of the damage to his left knee injured in the closing stages against Sunderland.

Vaughan left Carrow Road on crutches and Lambert admitted the former England U21 frontman has endured a wretched start to his Norwich career.

Vaughan missed the opening salvos of City's Premier League campaign with a knee problem before picking up a facial injury following a nasty elbowing incident during Norwich's recent home league defeat to West Brom.

'James was disconsolate and you can understand it because he has had really bad luck with injuries,' said Lambert.
