King's Lynn joint boss Gary Setchell insists Beckenham deserve Town's full respect ahead of today's FA Vase third round trip to Kent (3pm).

The Linnets are odds on favourites to book a last-32 tie at north east-based Norton & Stockon Ancients after hammering Raunds 10-1 last weekend on their return to league action. Setchell revealed Lynn's management decided against a scouting mission to watch Beckenham's recent league defeat – but Town's players will be fully briefed on the task at hand.

'No, we haven't watched them personally,' he said. 'There was a chance on Monday but we went to watch a player instead. I've spoken to people from clubs who have played them this season so we know what to expect. St Albans beat them 3-1 in the FA Cup but they were made to work all the way. We know it's not going to be won in the first 20 minutes – but we will show them plenty of respect.

'Rest assured, there's no one making travel arrangements for the next round or thinking we just have to turn up. We are not going to go there with an arrogant attitude.'

Setchell believes Lynn have reserved some of their best performances this season for the national competition, which leads all the way to Wembley.

'We know there are probably 30 teams left in the competition who all think they have a shot and we are no different,' he said. 'I think one of our best displays of the season came at Dereham. It wasn't just the fact that it was the FA Vase, but everything else that was at stake and the players raised themselves to another level – which for a new team was all credit to them. Then again we found ourselves at 2-0 down at home to Yarmouth and they had to dig deep and we came back and scored four goals.

'When the mindset has been right, we have performed well away from home. It's only when we haven't been at it that we got caught out at the likes of Long Bucky, Deeping and Blackstones.'

Jamie Thurlbourne (calf) is Lynn's biggest injury doubt but Danny White has been passed fit. Chris Bacon is ineligible and Brady Stone (hamstring) is poised to miss the next month of the campaign.

Captain Jack Defty will spearhead Town's attack after recent speculation the 25-goal hitman was set for a surprise Walks exit to free up funds to entice ex-Linnet Michael Frew back from Corby.

'There is no truth in Jack leaving whatsoever,' said Setchell. 'The Corby manager rang me up and asked would we like to take Michael for a month. That would mean moving a player out to balance the budget and it is not something we want to do.'
