Swansea keeper Michel Vorm insists the Capital One Cup winners must stop the Premier League rot ahead of Saturday's trip to Norwich City.

Michael Laudrup's side have lost their last three top flight games since that Wembley high which also earned them a place in next season's Europa League.

The Swans have been marooned on 40 points after beating struggling Newcastle a month ago, and Dutchman Vorm believes they have slipped way below their own standards.

'It's a very important game because we have lost three in a row,' he said. 'We had the same problem around the same stage last season when we got to 39 points.

'We have to make sure we have a good week's training and there is no option, we cannot lose. That has to be the mentality against Norwich. We have shown that mentality all season to beat almost everybody and now we have to look in that mirror, be honest and do everything to win a game.'

Vorm is also well aware Norwich have the upper hand in recent league games between the two former promoted sides.

'It is hard to say why they have done so well against us because they are not a top, top team, but they work hard all the time and we have to start by matching that,' he said.

'We have lost quite easily twice to them, so we know it will be a very tough game. We all know what we have to do to beat them - we need to start off well, we have to be 100 per cent focused on scoring the first goal and we have to try to make sure we don't concede.'

Swans' captain Ashley Williams admits the Welsh trail blazers are in a trough.

'We're having a bit of a wobble,' he said. 'We know it's only hard work, concentration and staying focused that will get us out of it. We've got to stick together as a squad, we've all been in these situations before.

'It's disappointing, we're as disappointed as anyone involved with the club and we've got to lift ourselves. We'll get our work done before Norwich, it's a tough place to go and we've got to get a win there really.'

Long-serving midfielder Leon Britton is adamant Laudrup's men have not lost their focus since landing the club's first major trophy in their centenary season.

'It's different if there's a cup final feel to things, it would be very different so maybe it might be the case that it does affect you in that way,' he said. 'But there's no way we're going into games thinking, 'We're done, we're on the beach'. We're too professional to even think like that. We don't want this season to fall away, we want to finish as high as we can and beat last season's points tally.'
