Norwich City must cut out the self-inflicted blows if they want to finish the Premier League season on a high, warned Paul Lambert.

Luis Suarez plundered a stunning hat-trick at Carrow Road but the Canaries yet again played a key role in their own downfall following on similar episodes in the post-Easter league defeats to both Manchester City and Blackburn.

Lambert could appreciate the purity of Suarez's strikes, but conceded his side need to eradicate the errors that have underpinned their recent run.

'I can't fault the effort but the manner of the goals is something I can certainly look at,' said Lambert. 'We made three bad mistakes for the goals but I won't blame any individuals or anything like that but as a team we lost three bad goals.

'We were beaten by the better team. We lost goals that were disappointing but there are not many times I have walked away from here disappointed - but after this game I am. That was a sore one. I don't like losing but you can't legislate for that. Up until the two goals it was a nip and tuck game. We gave the ball away ridiculously easy and you know he can score at any time.'

Suarez's clinical display was further evidence City are now operating against the best money can buy and on this occasion an expensively assembled squad who belied their recent Premier League struggles.

'Liverpool is a world-known club with fabulous players. I think they are in a false position where they sit in the league. They have some world class players,' said Lambert.

'We have come from League One and are trying to compete and beat them. You have to be right on the level or you get beat when you are up against that magnitude of team and that calibre of player.

'The finishing was great but it should never have happened in the first place.

'You can't give someone like that time on the ball and chances who can hurt you. He is a top, top player.'
