Goalkeeper John Ruddy believes Norwich City have enough quality to ensure Premier League survival, even if they fail to add to their squad in the January transfer window.

Manager Paul Lambert has been keen to bring in reinforcements but has so far hit a wall in trying to attract targets to Carrow Road as other top-flight sides try to flex their financial muscle.

But Ruddy pointed to the fact that City managed to chop and change their side over the Christmas period and still managed to pick up points to emphasise Norwich won't panic if there are no new arrivals.

'I think we showed that over the Christmas period,' he said. 'We had a couple of games but we used the squad very well. It gave players a chance that hadn't played very much this season and they came in and did an unbelievable job.

'We have got more than enough in the squad but if the gaffer needs to add to it he will and we will welcome them with open arms and they can help us stay in the league as well.'

Some fans would like to see the Canaries add to their defensive ranks but Ruddy believes that in Daniel Ayala and Zak Whitbread the club has the makings of a very good partnership at the heart of their defence while Russell Martin and Kyle Naughton also put in solid displays in the 2-1 win at West Brom.

'I think we've had the same centre- half pairing together for the last three or four games, which has helped, and they are creating a good understanding between themselves and me,' added the former Everton stopper.

'You know what you're getting from Russ (Martin). He's as solid as they get. Naughts has done a great job at left back he looks like he has played there all of his career.

'But we've got depth in the squad and if they do feel like they need to change it then they will and we've got players who can come in and do just as good a job.'

Lambert may be tempted to wrap Ruddy in cotton wool between matches after Declan Rudd was ruled out for two months with an ankle injury. While acknowledging it's a blow to lose their reserve goalkeeper, Ruddy believes that in Jed Steer they have another able deputy.

'It's a massive blow to Declan – he has been brilliant this season – it's not easy for someone his age to sit on the bench every week. But he knows how big it is for this club to stay in this league and he's delighted to be a part of it. It's a big blow to him and us as a team but hopefully he will come back stronger and a better keeper for it. Jed has had a good loan spell at Yeovil and every time he has been called upon to train with the first team he has shown what he's about. 'He is a very good goalkeeper.'
