King's Lynn joint boss Kevin Boon is looking for the perfect FA Cup tonic against higher league Quorn in today's second qualifying round tie at The Walks.

Town's unblemished start to their UCL Premier Division campaign ended against title rivals Long Buckby last weekend but Boon is relishing the chance for cup progress against a side propping up the Northern League, Division One South.

'We've spoken to a couple of people in that part of the world but they have just brought in a new manager who comes with his own ideas,' he said. 'They haven't won a league game but this is the FA Cup and everyone knows what that means. I honestly believe we are the underdogs because they are a step four club – people must remember that. We won't take anything for granted.

'There is decent prize money again and I think coming in as early as we have done in this competition has benefited us because we could be entering today and going straight out again. We have already enjoyed a bit of finance from it. The incentive is there for even bigger games at The Walks if we continue to be fortunate with the draw, but this is the only game that matters and we want to put things right after last weekend.'

Town have injury concerns with Jamie Thurlbourne (hamstring) and Stuart Wall (ankle) major doubts but last season's top scorer Jack Defty (foot) is set to play and skipper Ross Watson (hamstring) are back in the fold after a lengthy lay-off.

'Ross is a bit of a talisman for us,' said Boon. 'He missed four or five weeks but in that time he has been at every training session. He could come in and do a job for us in that central midfield area. Everyone knows Callum Reed was the man we had identified - that didn't work out and we are still looking. We have spoken to a couple more players this week but they either want silly money or we don't feel they are quite what we need. Ross played at step four for Stamford so he is more than capable of doing a job.

'I've also had a chat with Jack and to be fair to the public he is only about 90% fit but he has said he is willing to play because he knows how important it is. He got some stick last week, but the rest of the lads have to help him out. Jack is decent on the floor as well so we don't need to keep hitting balls into the air all the time.'

Boon admitted Lynn fell well short of expectations against a well-drilled Buckby side.

'We just didn't perform on the day,' he said. 'We missed a couple of chances on the day, Danny Beaumont hit the bar, Spriggsy (Steve Spriggs) had a couple of one-on-ones. Credit to Long Buckby, they were disciplined, well organised and we found it tough to break down.'
